Energizer and Duracell both have Li (lithium) versions of the CR2032 battery. I've used the Energizer and found they last a fair bit longer than the normal variety but they are harder to find and cost a little more.

Ski length - XL (currently only Large is in stock 143-187lbs)
Boot size - 9UK
Pole Length - 140 (currently only 150 and 155 are in stock)

In the upper right corner of the page you can start a chat with live person who can check whether or not the sizes you need will getting stocked any time soon.

Vitane signifies the women's version in Salomon products.

Lighter. The pair of 8.5's I had came in at 11oz each.

Waist. It's a fairly new design from Nathan that comes in 3 sizes instead of a "one size fits all" approach. Reference the Tech Specs on the right side for the appropriate size.

The short answer is no. If you are really good at waxing you could take a skate ski and make it work for classic, but it would be less than ideal. A waxless classic ski (the kind with scales in the middle) would be extremely taxing to skate with. If you are looking for some good cross training for cycling and go skate style. I ditched the trainer years ago in favor of skate skis and loved it. It is much easier to get an aerobic workout from skating right away than it is from classic style. I would also suggest you take a lesson so you are less likely to form bad habits that become hard to break down the road.

6 oz. according to quick search.

I wore an 8.5 in the CD's and the 8.5 Masochist feels perfect. I did run in an 8 for a while but the toe box felt a bit cramped and I started turning toenails black.
Go with 8.5.

It used to be that traditional frames flexed a little bit more since the overall geometry was bigger. However, with as stiff as frames have been getting the difference in flex between the two would be minimal. Sloping frames do tend to react a little quicker when cornering and accelerating than traditional frames but it sounds like that's not a big priority for you.
I would say go for the traditional if you're going to be doing longer rides without racing much.

Yes it does, but you cannot see the vertical gain/loss until the exercise is downloaded to the software.

The tech specs are wrong, the Observer is not PC compatible. The specs above also indicate that it does not have a chronograph, it does.

I own the masocshist's as well as the montrail streaks and for the non-technical stuff I prefer the streaks. The Masochist are a little bit stiffer and a little bit narrower than the Streaks but they weigh the same. If you're looking for a similar fit but a little more comfort then go with the Streaks, you won't be disiappointed.

All Aluminum SIGG bottles are made in Frauenfeld, Switzerland. Frauenfeld is one of the eight districts of the canton of Thurgau, Switzerland. Its capital, and the capital of Thurgau, is the city of Frauenfeld.

It will work just fine with a 16" bike. When my kids were younger I put a 12" bike on this rack. Now we take their 20" bmx'ers with us camping all the time using this rack.

I have the Masochist and the Streaks. The Masochist has a narrower toe box. My feet are pretty narrow so the Masochist works for me but I can immediately tell I have more room when I put on the Streaks.

Yes. It has two small standard type screws on each side that are easily removed. You would have to replace it with something made by Suunto though since it is a proprietary design. BC carries a velcro strap that IMO is more comfortable than the plastic band that it comes with.

No, according to the Suunto website the CODED belt is only compatible with the t1 coded and t1c. You would need the ANT for the t6.
http://www.suuntowatches.com/Suunto-Comfort-Belt.pro

Yes. I machine wash my smartwool shirts in warm, with a cold rinse, delicate dry.

Yes. A standard mtb rim is 26in so you'll be fine, just make sure to pick up a smaller diameter tube to match it. Something like a 26x1.25 should work.

I own this headlamp and I have used it until the batteries have completely died. When the battery is getting low the light will blink twice approximately 10 secs. after turning it on. There is also a little orange light on the side that indicates a low battery.
I left it on the highest setting after the low battery warning and it lasted about 2.5 hours. Of course if I had it on the lower light setting it would have lasted longer.

Not completely true.
1st, if you change to this particular crankset you will need to get a matching bottom bracket.
2nd, you might be able to tune the front derailleur to shift a double instead of a triple but it will not be very smooth or consistent, you would be better off getting a front derailleur for a double instead.
3rd, your current rear derailleur is a long cage model which is used to handle the longer chain req'd by triples. Running a double would shorten the chain and cause your current derailleur to not function properly.

No. The tech specs along the right side indicate that it's not.

Not rechargeable, it's a battery that you replace. You can do it yourself if you have a small phillips screwdriver or you could take it to a jeweler to have it done (they usually don't charge anything extra if you buy the battery from them).

Based on your weight I would definitely say yes. However, riding tubulars as your "most occasion" kind of wheelset is an expensive tire option, since you would have to carry an extra tubular tire in case of a flat. You might want to consider a clincher wheelset instead that takes a standard tube.

Pilot boots are made for Pilot however they can fit into most Profil bindings, due to a small space behind the front of the boot for the other axis.
I use my Pilot boots on an older pair of skis that have Profil bindings all the time.

No, afraid not. Your bindings are SNS-Profil type while the boot is NNN, which is not compatible.
When looking at boots look for the SNS Profil compatibility.

The Vitesse comes in Medium width only.

No. If you would like distance you will need to look in the GPS section for the Garmin brand or the watches section for the Polar or Suunto models.

47 x 30.5 x 10.5 inches

Unfortunately height is not the only factor for determining pole length. However if you are just getting started you can get a good fit by measuring the distance from the floor to the tip of your nose.The Vitane are supposed to be women specific while the elite's are mens. On that note I've never been able to tell the difference between a womens specific and mens specific ski.

Yes.

You can use this with an 8sp setup and it will work pretty good. If you want it to work better then use a 9sp chain, which will work with an 8sp cassette just fine. The only concern with that is that the cassette isn't too worn out and mated to the chain that's currently on there.I also own an old steel frame that I truly love and one thing to consider is that a stiffer crankset will only expose how "soft" the steel has become in your frame. You can check this by standing next to your bike and tilting it away from your body. Put the pedal closest to you in the 6 o'clock position and step on it while looking down at the bottom bracket. Check for flex in the frame or crankset.

Use your inseam size (inches):31 small, 32.5 med, 33.5 large, 34.5 x-large

This particular watch will work just fine without the HR monitor strap as long as you don't want to keep track of your HR. If you are asking if there is a watch out there that tracks HR without using a chest strap the answer is no, at least not with any consistency.

No, you would not want to carry this on a ride. If the product description includes "floor pump" this means that it is not meant to be carried on a ride.

Looks like the 2007 model is permanently out of stock. Comparable Patagonia bags are the Lightwire and Half Mass.

No, you will need an adapter. Unfortunately I could not find it here on BC but they are widely available for ~$20. Search online for Side Cleat Adapter...

No, you will need an adapter. Unfortunately I could not find it here on BC but they are widely available for ~$20. Search online for Side Cleat Adapter...

Should be listed as 53 x 39.

Not a dumb question at all. Yes, this will work on your Felt S32.

This will do everything but true maps. The map screen shows a track of where you've been and any waypoints that are around your location and that is all. If you want a true looking map check out the GPS units on the previous page and look for the mapping option that is listed as "Yes" in the specs, located in the upper right side of the page.

No. Polar HR straps are coded for Polar watches.

Yes, they will attach to the small screw mounts down by the dropouts.

On a road tire yes (700c).

Yes.Check out http://www.sheldonbrown.com/bbsize.html#105

As long as the Fischer boots are a pre 2007 model then they will work. For the 2007/2008 model year they switched to the NNN system.

Mavic doesn't publish a weight limit, I know a couple of riders that are over 200lbs that haven't had any issues to speak of.They ship with the following:Bearing adjustment tool (rear wheel),BR301 quick releases,Rim tape,Spoke wrench (rear wheel),Spoke wrench for aerodynamic spokes (rear wheel),User guide and warranty card,Valve extender

The streak runs a bit big for me. I wore an 8.5 in the Continental Divides, and Hardrocks. I wore an 8 in the Vitesse. The 8.5 Streak was waaay to big for me, the 8 is perfect. Hope this helps.

It sounds like your setup has a square tapered bottom bracket, unfortunately BC doesn't carry square tapered BB's. For your bike you will need a 68mm width shell, english threaded, with a 110mm length spindle. You should consider heading down to your local bike shop for help with this.

The smartwool adrenaline line offers a bit more cushion than the PhD's. I also like the Darn Tough brand that they also have here on BC (coincidentally Darn tough's are made in Vermont). They last forever good for cold or hot conditions and have cushion comparable to the adrenalines.

Yes. Any 700c wheels with a shimano cassette body will fit.

Sorry, the software is PC compatible only.

The chainring size listed above is 52x39, which is not right. This is a standard 53x39 crankset.

No, they are 44x55.

Check the inside of the crank arm for the size you currently have. Should be one of the three listed in the options above, 170, 172.5 or 175, which is the length of the crankarm in mm.

Yes, they come with cables and housing.

Check out http://www.swixracing.us/nordic/ for waxtips on the 2009 Birkebeiner Wax Recommendations.

No. Even though the description does not specify, the picture indicates this is the short cage version. The long cage version has the same 7800 model number except with a GS added on, i.e. 7800 GS (long cage) 7800 SS for short cage.It might be worth giving them a call to go check the actual box in the warehouse to see if it is a GS model or not since it's not specified.

Yes. Just loosen the two hand tightened fasteners, fold down, re-tighten.

Pair.

Give them a call or click the "Chat Now" in the upper right, could just be an oversight...

This cycling computer comes with the heart rate monitor strap only. The speed, cadence, and power accessories would have to be purchased separately. W.I.N.D. speed and cadence run anywhere from $35 to $55 on other sites.

It comes with the .5L bottle only. The bottle fits inside of the laptop sleeve on the inside. Looks like you could add a bladder if you wanted to though.

Can you turn the blue ring on the bite valve 90 degrees and get flow? Another thing, on these types of bite valves you you have bite down quite hard the first time to open up seal, you should hear a small pop. After that the bite doesn't have to be that hard to get fluid to flow.

If you are only tracking heart rate and not speed, cadence, etc. then go with something a bit less expensive like the RS100. You can upload results to your computer and track your progress as well as using it for other activities.If the stationary bike is similar to to what you find in a gym it really isn't worth the trouble setting up the system on that kind of equipment. If the stationary bike is a bike that you can ride on the road and you are using it on a trainer then you could use something like this.

No. These are for a 10-speed drivetrain

I don't own the bag, but given the dimensions at 30" wide I would say it would be a pretty tight fit. I think you would definitely have to remove the tires in order to make it fit, and even then the rims would be stretching the bag to it's limit. FYI, a bag for a road bike should work with 29er since the rims are the same size, just make sure to check the length of the frame against the length of the bag.

No, you'll have to step up to the 305 model for HR (Item #GRM0072)

Generally speaking, the length from the floor to the tip of your nose. There are many factors that make it hard to set standard guideline, but that method will get you close.

Yes, the cassette body needs to be specified either Shimano/SRAM or Campy. When you are ready to order click on the online chat to make sure they get this option correct since it's not specified directly in the options.

Klister wax or in this case, base prep for Klister is for Grip on classic style nordic skis. This is applied in the kick zone (the middle) of the ski. If you want glide wax that can be applied without ironing try one of these:http://www.backcountry.com/store/TOK0007/Toko-Express-Blocx-Rub-on-Wax.htmlhttp://www.backcountry.com/store/TOK0006/Toko-Express-Pocket-Universal-Liquid-Fluoro-Wax.htmlDakine has a few but I don't have any experience with that brand.

I extended the straps on mine all the way and the measurement came to 56in. You should measure around the broadest part of you chest to see if it exceeds 56in. If so then it wouldn't fit.

There shouldn't be any reason a BMX wouldn't fit in this bag. Measure the wheel base of your bike (drop out to drop out) just to make sure that it doesn't exceed the length of the bag, 46in.

Do you mean F7? If so then the answer is yes. As long as your Mtn bike has 26in wheels and disc brakes these wheels will fit.

170cm. The sizing chart referenced above really isn't clear. My wife was just fit for rossi skate skis last year and she's in your same weight range.

No, these wheels are for use with disc brakes only. The Tarpon uses v-brakes. When you are looking for wheels check out the hub/brake compatibility on the right side of the screen, for your bike it should read "Rim Brake".http://www.backcountry.com/store/MAV0010/Mavic-Crossmax-ST-Wheel.html

Just below the options drop down (in the upper right) there is a link to a sizing chart from La Sportiva. It appears that women's size 6 = 37 euro.

The Mediums are the heaviest weight in the Adrenaline line. The next step up is the Trekking line which is heavier.FYI, I was a big fan of the adrenaline's and switched to the PhD's. I was disappointed with how long they lasted, lack of cushion, and the amount of dirt that would accumulate on my foot. A friend of mine suggested the Darn Tough brand and I've never looked back. Same price range as the Adrenaline's but perform much better than the PhD's or Adrenaline's. Try them, you won't be disappointed.

The price is for a pair. These bindings are solid and will last you a long time. They are definitely a good choice for beginners.

It's hard to say if these would feel like your old boots, but these are pretty decent for the price. This boot is compatible with the NNN binding system that it sounds like you're currently using.

174's are rated for up to 133lbs, 182's are good from 133 - 154lbs. If you are going to be skiing a higher percentage of ungroomed terrain vs. groomed then I would recommend 182's. 174's if you will be on groomed trails more.

Yes. Look Keo cleats are 3 hole patterned, the same as these shoes.

In short yes. The thing to look for on the boot is a single bar that locks on to the binding near the front of the boot. The other type of Salomon binding is called the SNS Pilot and has two attachment points instead of just one.

The watch will work without the belt, it just won't record your heart rate.

A set of 4 for $5.

Yes, full metal edges.

If the original has never been removed it can be little tight. Run the attachment point under some cold water, grab the tube near the attachment point to the bladder and give it a good pull. To put the new one on I usually just get the ends wet and push it on while giving it little 1/4 turns back and forth.

These would work fine. MTB shoes are a bit easier to walk around in than road shoes. These shoes do not come with cleats so you will need to pick up some of those as well. Check the bikes at the gym for the type of pedal, more than likely it will be an SPD. Cleats can be found here:http://www.backcountry.com/store/SHI0122/Shimano-America-SPD-Cleat-Sets.html?

Yes. The thing to look for on the boot is a single bar that locks on to the binding near the front of the boot. The other type of Salomon binding is called the SNS Pilot and has two attachment points instead of just one.

You only have to wear the strap if you want it to record you heart rate.The G3 is included.Water resistant to 60ft (20m).

SNS Pilot. However, I have successfully used my pilot boots with some skis that had profil bindings, you just can't use profil boots with pilot bindings. Hopefully that makes sense.

No, these are not 3-pin compatible boots, these are NNN (New Nordic Norm) compatible.For a 3-pin boot try:http://www.backcountry.com/store/ALP0195/Alpina-Blazer-Touring-Boot.html

Specs on the upper right side of the page read 25oz (ounces).

The gray plastic bubble on top lifts off on a hinge to expose the tip of the bottle which you drink out of. The water bottle tip then slides up or down to allow flow. The gray bubble piece can be removed in order to make it a little more accessible.We always had water bottle kicking around while my kids were small and they never had a problem drinking out of water bottles. If your 2 year old can drink out of a sippy cup then they can handle a water bottle.

IMO it is very easy. It comes with a small hex key (wrench) that is used to clamp the bracket to the bar. The first time may take 15 minutes or so, but after the initial install they are very easy to take on and off. Be warned, without lock cores (also easy to install) you risk someone stealing the rack and whatever it might be holding at the time.

This one does not come with the cadence sensor, which is usually an additional $25 to $35. Search for Polar cadence sensor CS series.

Mine are slightly older than the one pictured and this is what I did to get it off:Use a large flat screwdriver to push the clip (the part the boot locks into) forward/open. This will relieve the pressure on the boot release button. Use a second large flat screwdriver to pry the button off of the binding. Be gentle. Use a Phillips #3 to remove the three screws that hold the toe piece.

No, these bindings are made to fit the newer style boot with the single bar running perpendicular to the ski. This particular binding is made for backcountry ski touring (hence the BC)which would stand up to more aggressive downhill skiing.Here's a place that sells 3-pin nordic bindings:http://gearx.com/product_info.php?products_id=36472?ref=base

7.5"/19cm diameter about 2" deep.

1 lid, fits both pots and doubles as a plate.

Both the 7mm and 8mm will fit on the same seatpost even though the diameter is different. The other main difference is the material that the rails are made of is different, making the 7mm lighter (see below).7mm Rail: Clamp Style: 7/8" Straight, Published Weight(claimed): 315 g, Width: 135 mm, Length: 290 mm, Rail: Kium8mm Rail: Clamp Style: 7/8" Straight, Weight: 407 g, Width: 135 mm, Length: 290 mm, Rail: Magnelium

For this ski the 190 or 195.Cross country skis are sized according to weight. Ideally you want to weigh just enough to make the ski flex flat and make contact with the snow. Each set of skis will have a different amount of camber (flex) with a different weight rating. The best advice is to check with each ski manufacturer before you buy.

No a pump is not included with the sleeping mat. Self inflating type that you can supplement with a few breaths.

The stuff sack that it comes with is 8.5 x 18" but it could be compressed a bit more with a smaller stuff sack.

This watch will not track distance or heart rate. If you want to stick with Suunto then check out the link below (there is also a great review on that page that compares the Suunto and the Garmin 405)http://www.backcountry.com/store/SUN0079/Suunto-X9i-GPS-Watch.htmlPolar also has a few watches: RS200, RS400, S625X, S725X, but you need to buy the optional accessory Polar G1 GPS to track distance:http://www.backcountry.com/store/POL0061/Polar-G1-GPS-Speed-Distance-Sensor.htmlAnd finally the Garmins: Forerunner 201(kind of big), 301, 305, and 405:http://search.backcountry.com/exec/?mv_session_id=XAI5NqKd&aff=1&q=garmin&x=0&y=0

No. The ignition does not offer water protection.

The standard portable tanks that can be found in grocery/hardware/outdoor stores screw on to the attachment. Usually cost around ~$5, hold 16oz of fuel, and burn for ~3 hours depending on how high you set the flame.

If you look not really that hard at the picture, you'll see the collar part in the upper left. It's kind of both.What is pictured above is indeed a leash. The loop in the upper left is for your hand, the carabiner clip is to hook on a collar. Judging by the price, if you purchased this you would get a collar not a leash. My guess is that the picture is matched up with the wrong item.

I would suggest the Petzl e-lite, a little less expensive and quite a bit lighter. It does take watch batteries (cheap and commonly found in grocery stores) that last for 40 hours of use. Mine has been taken over by my wife for just such a purpose, reading in bed.

Yes, the Polar RS200 will keep track of each interval (lap) and all of the data that goes along with the lap, including avg HR, max hr, and time spent in each target zone. If you buy the add-on foot pod you can get distance statistics from each interval as well.

Road bike shoes have a stiff sole in order to transfer power to the pedals. The downside of stiff soles is that it makes the shoes hard to walk in. MTB shoes tend to have a more flexible sole that makes them easier to walk in. So the choice of shoe really depends on how much walking you intend on doing in that shoe. More walking and I would buy a MTB shoe.

27 oz for the big pot, 20 oz for the smaller pot, and about 9oz if you chose to use the frying pan.

Yes. All front hubs are the width.

If you don't want to void the warranty then you need to send it back to Polar. That being said the battery will last longer than the 2 year warranty so if you're brave and have some very small screwdrivers you can replace it yourself. I have done this successfully on my S710 several times now. The battery was a little tough to find, but I found a battery specialty shop that carried this medical grade battery. One thing to be careful of, when lifting off the back of the watch there is a rubber gasket that keeps the water out, just make sure it is seated correctly when you put it back together.

She would be a solid Medium. I'm on the edge of medium to large (mens 8.5) but the medium works best for me.

If you want something that is currently available from Backcountry check out the the Toko Dibloc LF Blue, rated -10 to -30 celsius.

The color choices indicate that these are the men's models. However, your wife could still wear these in in men's medium for womens size 8 1/2.

It has a UPF rating of 15 (approx SPF of 40) which means it blocks 93% of UVA and UVB rays. UPF ratings are used to describe how much of UV is absorbed by the fabric and not your skin.

Trail shoes tend to be very stiff with a protective layer for obstructions on the trails. I've used my trail shoes to run on the road from time to time and it becomes hard to land softly, especially if you run fast. The stiff sole forces your foot to almost "slap" the hard surface, causing more stress on your lower legs. If you are running exclusively on pavement/concrete go with a road specific shoe. If you are using them only occasionally on the hard surfaces then they will probably work.

Smartwool makes sizes med through XL for men and women. Backcountry must be out of everything but XL at the moment (12/14)

Socks are 75% wool, 24% nylon, 1% elastic.Shirts are 100% wool (smartwool) different blends depending on the the type of shirt.

The coded T31 transmitter is included, as stated in the specs above.The way the watch and computer talk is called Uplink. It is software that utilizes the computer's sound card and speakers to facilitate communication. Generally the speakers that are found on laptops do not work.I used it with success on an older Polar watch with separate desktop speakers.

No. You're supposed to rinse with warm soapy water at the end of each day. If you let it go and really need to clean it you can use baking soda and vinegar or SIGG make cleaning tablets and a special brush.

Batteries will last ~45 hours, depending on the brightness settings you use. I've been able to find batteries in my local grocery store for $3 to $4. Just about anywhere that sells watch batteries and/or hearing aid batteries will carry them.

I assume by "no wax" you are referring to classic style skis with the scales in the middle. If that is the case your buddy is right. Wax the tips and tails and you will notice a difference.The swix LF wax is a little over the top for this type of application, you might consider the Toko Grip & Glide Wax or one of the cheaper glide waxes. Higher end waxes are made for specific temperature ranges of snow. Lower end waxes accommodate broader temperature ranges but are generally slower.

There's no reason you couldn't use this shoe for spin class. However, if that is all you are going to be using it for then you should consider a less expensive mountain bike shoe that is easier to walk in. Road shoes can tend to be a little hazardous on smooth surfaces such as tile.

This boot is compatible with the pilot system and the profil system. I have successfully used my pilot boots with some skis that had profil bindings, you just can't use profil boots with pilot bindings. Hopefully that makes sense.Before you decide on a pair of boots check the manufacturer's website to see if they are compatible with the binding system you are using.The pilot boot (and binding system) uses two pins in the boot and two axes on the binding instead of one, like the profil system.

15 ounces (including 3 "C" batteries), 7 x 3.25 inches.

Almost all MTB pedals come with cleats that are compatible with the 2-bolt (SPD) mounts. Shimano, Time, Crank Brothers, and Speedplay pedals are all compatible with the 2-bolt system. When you are looking at pedals the manufacturer will indicate if they are SPD compatible/2-bolt compatible, the same thing.

A 15 inch will fit in the medium. If you have a pad that you will be using with the laptop (to protect it a little better) I would go with the large. My wife has a medium and I have a large. I've found that I never have enough room for more than 1 medium size textbook and the laptop with the medium size bag. I almost always grab the large in case I need to stop at the store or stash more stuff.

The regular is: 70" x 20"The Deluxe is : 76" x 26"Looks like if you don't mind your toes hanging over the edge of the regular you could use that one. I would think that you should measure your shoulder width in comparison to the pad width to help with your decision.

I've used mine indoors and outdoors without feeling a difference in temperature. I have a 30 degree bag that I typically use and I'm generally pretty warm when I sleep, even when the temps dip below freezing.

3.5" diameter x 11.25" tall. As far as fitting in an auto, I suppose it would depend on the diameter of your cup holders.

It really depends if the towers have locks or not. If there is a lock, you'll need the key to unlock the tower before you can release it from the roof. Once the tower is released the round metal part on top of the tower be free from the bars. Just remove the caps on the end of the bars and slide the towers off the end. Before you start look closely at the ends of the bars. If they appear fatter than the rest of the bar they have rusted (this is only a problem on older bars, new bars are now galvanized) and will present a real problem to get off. I had to basically destroy the end of the bar in order to get the towers off, not fun.
