    Solid training.

    As much as you love your 'cross wheels, knobby tires just aren't as fun on pavement when you're trying to throw down for county sign sprints in a pack of skinny tires. What your 'cross bike needs is a solid set of affordable aluminum hoops like the Mercury Wheels M1 Disc Brake Clincher Wheelset for a dose of roadie speed to knock out summer base miles and pastry-fueled group rides. Made from lightweight yet durable alloy, these wheels are the ideal training companion to give your 'cross bike new life on the road and let your race wheels take a break from the elements.

    The M1's 18mm internal rim width belies a road-focused intention to provide a solid platform for today's trend of 25mm tires, and tubeless compatibility empowers those of us looking to ditch the tubes and reap the benefits of lower tire pressure and a smoother ride. While we wouldn't necessarily recommend mounting 33mm 'cross tires on rims this narrow, the tubeless compatibility and a quick consultation of the ETRTO charts indicate that they'll also serve as pit wheels in a pinch when your usual spares are at the shop for maintenance.

    • A sturdy aluminum disc brake road wheel
    • Aluminum rim construction balances strength, weight, and cost
    • Shallow rim depth remains stable in the wind
    • Ideal internal rim width for today's wider road tire trends
    • Laser etched logos won't peel away
    • Compatible with 6-bolt disc rotors
    • Item #MCW000L

    Sturdy and Fast wheelsets!

    Familiarity:I've put it through the wringer

    Upgraded my OE wheelset on my Trek. Very strudy and well built with even tension; 9 months of hard riding and everything is straight and true. Running Conti GP 5000 28mm and the feel good. Great deal.

    Crazy good wheels!

    Familiarity:I've put it through the wringer

    I needed a new set of alloy wheels to replace my OE wheels on my Giant. First off these wheels are a tough as nails. I’ve been rough on these and they’re still completely true as the day I received them. Now over 2000 miles on them with no complaints. Highly recommend if you need a sturdy all around alloy wheelset.

    I use these M1 on cyclocross bike. Over 3500 miles and no issues at all. Have been running 40c tires on them and they've been great. No problem with tubeless setup. Highly recommend.

    Nothing but drama

    Familiarity:I've put it through the wringer

    I cannot recommend these rims. They are a lot like Seattle, when they work they are great, it is just the amount of time dealing with rim tape alternatives, multiple flats, and LBS trips, make them un-reliable. There is clearly something wrong with the engineering of the spoke holes relative to the bead seat that caused the pressurized tire to move the tape. My advise is if you don't want to worry about flats, don't buy these rims.

    Pretty Pretty Good

    Familiarity:I've put it through the wringer

    They may not be the lightest wheels on the market but they sure do roll fast. I've been using them on a CX commuter bike and they've been solid. They fit 40c tires pretty well, although setting them up tubeless took a little extra work. The hub bearings have held up great to very poor conditions and have stayed true. Would definitely recommend

    I’m having issues setting these up tubeless, what kind of tape did you use?

    Look no further...

    Really wish I would have seen these earlier! I have a set of their 55mm clincher rim brakes wheels on my Super Six. Love them! Braking is awesome with the Mercury pads, but they do wear quickly! An understandable trade off as the pads are reasonably priced. These are a much better option than CN carbon wheels...

    LOVE THESE WHEELS.

    I upgraded my Ridley X trail to these from the stock wheels and I couldn't be happier. Very stiff and well made wheelset. I have been running Schwalbe 35mm on them and they feel great. So far, so good.

    Spacing might be a bit odd

    Familiarity:I've used it once or twice and have initial impressions

    i bought these as road wheels for my 2018 Giant TCX w front and rear 12mm thru axles. When I swap out the stock wheels for either my Stan's Iron Cross or Grail, all wheel sets drop right in and I think I barely had to tweak the rotors once and I don't have to adjust the shifting between the rear wheels. But for the Mercury, the 12mm front TA wouldn't go through. Well that's weird. Turns out the 12mm hub adapters for the Giant stock wheels and Stan's have an OD of 19mm, but the Mercury 12mm adapters have an OD of 21mm (measured w digital caliper). That 2mm is enough so when the hub seats in the fork, the axle hole is off center with the holes in the fork and the TA won't go in. On the back, when I first put in the wheel, right off the bat it's clear the disc brake rotor will need a spacer, and the shifting is off. Neither of these issues are unusual swapping different rear wheels or hubs, but there it is. I emailed Mercury and didn't get a reply which is disappointing. But as others have suggested, these wheels hit a sweet spot between price and quality, so I'm going to have the front adapters machined, space the rear rotor, and deal with the shifting.

    Hey Randy - You may want to reach out to support@mercurycycling.com They do have road disc specific end caps that would solve the issue and keep you from having to machine a fix. They're usually really responsive.

    Hey Randy, I haven't heard of a spacer for the rotor being needed before. I'd like to know if there is something more going on here. Would you mind sending your info over to support@mercurycycling.com? We'll gladly get the front end caps that you need and figure out what could be causing the rear to not fit properly.

    I had sent info to info@mercurycycling, not support - my mistake. I did get a reply back from Mercury. They said one option is to adjust the brake caliper when changing wheels, otherwise after the machining and spacing it sounds as if I'm squared away.

    I have the same issue with a Ridley X-trail I bought here as well. I called Mercury and they are sending me a set of the 19mm end caps

    WOW!

    Familiarity:I've put it through the wringer

    What a set of wheels. They arrive in a double wall box first of all which is much appreciated due to my last set of Easton's showed up all banged up with holes through the box. I know it wasn't Easton's fault, but..... The M1's have their logo laser etched onto the rim which I haven't seen before. Setting up for tubeless was a snap and only had to tape the spoke holes and valve hole to make them airtight due to the rim being laser welded. Honestly, I couldn't find the seam at all! The width is perfect for my 28mm tires that have seen approximately 1K miles.

    I bought these about 8 months ago and have put over 1700 miles on these with no issues. Have been running 40c tires on them and they've been great. I haven't had to true them at all. Super smooth wheelset.

    I picked these up for my Gravel bike and couldn't be happier. I'm running Schwalbe G1's on them. They have stayed true, run strong all over the trails of CO. Also built in the USA. I would highly recommend these wheels.

    Great Spare Wheelset

    Familiarity:I've used it several times

    Picked these up (like everyone else) to use as a spare set for my CX bike. At the moment, I have my road slicks mounted to them - 700x25mm - so that I don't need to mess with my tubeless gravel tires each time I want to put in some pavement miles. For the price, you can't beat these wheels: purchased a cassette and two rotors to further make my life easier and the total cost still came out just south of my rear Zipp wheel. It'll be nice having a spare set when CX season starts, if my husband doesn't steal them for his bike.... that's the unforeseen downside of having a wheelset that can use both a QR and 12/15 Thru-Axle! As has been noted, the bzzz sound from the hubs isn't quite like a swarm of angry bees, but it's still noticeable. On my last ride, I found myself pleasantly surprised at how smooth they are. I like the fact that Mercury tries to manufacture as much of the wheels in the US as they can, too. If you're on the fence or upgrading a set of wheels for the first time, just do it! (I haven't tried messing with the tubeless setup on these wheels and probably won't bother, given the other reviewers' experiences.)

    Great wheels, great price!

    Familiarity:I've put it through the wringer

    You really can't beat these for the price. I got these as a second set for my gravel bike to more easily switch from 40c knobbies to 28c road slicks. I'm running these wheels tubeless with 40c WTB nanos in the rear and 40c Maxis Ravager in the front somewhere around 35-40 psi and they are great! So great in fact that I'm getting a second pair for my 28c Conti gatorskins (not tubeless, unfortunately). The wheels are light, run true, and have a descent "buzz" sound from the freewheel (not Chris King great, but better than the stock Niner wheels that came on my RLT 9 steel 2-star build). The only issue with running these tubeless is you might need a better rim tape. I had my LBS set them up tubeless for me, and they had to replace one rim tape, but were able to use the other. Since I had it done for me, I can't personally speak to how easy or difficult they are to set up, but they've held air pressure VERY well since getting them set up.

    Great price, tubeless and spoke issues

    Familiarity:I've put it through the wringer

    UPDATE: After riding these for over a year now, I can say I'm disappointed and would not buy again. Although they hold air when setup tubeless, there is a constant leaking of sealant at various spots around the rim. They just don't fully seal - even with TL tires. I've also broken two spokes on the rear wheel. Would not recommend. First off, the sale price on these is unbeatable. For under $400, I can't imagine finding a better set of wheels. Roll nicely, well-built, look great, quality hubs. My only issue is with the tubeless setup. They were challenging to setup tubeless in the first place, and have continued to be disappointing as far as holding air and being burp-free. I have sealant stain on my sidewalls after every ride, regardless of PSI. That being said, I'd still buy these wheels for the sale price and just deal with the tubeless challenges. FWIW, I'm running Panaracer GravelKing SK 35s. On my previous Stan's rims I had no burping or leaking.

    Hi Gary - Sorry to hear you had / are having tubeless issues. If you still have the wheels give us a ring and we can see about offering some assistance. Thanks!

    I currently have skewers. Will this wheel work with skewers instead of thru-axles?

    Hi Patrick, These will not work with skewers. It does not appear that Mercury makes replacement end caps to allow these to work with skewers either. Give us a call at 888-276-7130 if you have further questions!

    the M1 disc are shipped with QR adapters (in addition to 12mm, and 15mm) for the front, and thru axle only rear. most current CX or road disc bikes are 12x142 rear, but axle standards for the fork havent been nailed down yet, hence why we provide the front options. if you need the rear adapter, we have them available online at- https://mercurycycling.com/collections/accessories/products/mtb-qr-rear-axle-end-caps

    can these be setup for front quick-release?

    Yes. You'll just need the QR Front End Cap and QR Rear Axle/End Cap. I believe Competitive includes the front end caps, you'll just want to purchase the rear axle/end cap from Mercury: https://mercurycycling.com/collections/accessories/products/mtb-qr-rear-axle-end-caps

    Almost certainly yes. On my bike I have the rear setup with QR, I believe the front can be too. The hubs are very flexible.
