Alloy never looked so enticing.

The Yeti SB-66 was the first frame to receive Yeti's Switch Technology, a rear suspension system that is designed to keep the rear of the bike neutral , as the shock moves through stages of compression and decompression. The 152mm travel alloy SB-66 continues to push technology within the parameters of an affordable, all-mountain bike.

Full suspension bikes have always been great at one thing, going downhill. When trails start to lean skyward however, more often than not, power that you're trying to put into the drivetrain is zapped by the bounce of the rear shock. Yeti's Switch Technology is designed around an eccentric pivot system in the lower pivot. It is in basic form, a mini dual-link system that moves in two directions-hence the "switch" designation. As the rear suspension compresses into its travel, the eccentric design rotates counter-clockwise as viewed from the drive-side of the bike. It moves this way through the first 100mm or so of travel to provide an anti-squat, neutral characteristic to the suspension. Once mid-stroke is exceeded, the technology changes direction and rotates clockwise. In layman's terms, this keeps the "growth", or horizontal movement, of the chain stay at a minimum so that you get reduced pedal kickback. It creates a solid platform to pedal on, much as you have with a hard tail frame.

The bottom bracket, eccentric, and lower pivot for the swing link are all machined into a single, forged aluminum structure, which means that, on every bike, alignment is perfect. This translates into a rear swingarm that moves freely throughout its travel range, and to a longer life for the Enduro Max sealed cartridge pivot bearings.

The shaping of the frame complements the Switch Technology. The seat stays flare in the vertical plane towards the dropouts. On the left side, this helps distribute loads from the post mount. The larger cross-section handles compression loads without flexing. The down tube is ovalized at the bottom bracket to enhance stiffness, and it features flattened sides to channel and distribute stress from the shock mount.

Since Yeti partners with FOX for its World Cup team, it's no surprise that its frames use the latest FOX engineering. The FOX FLOAT CTD features a Kashima Coat for a slick, durable finish which allows the shock to respond faster. The CTD offers three pre-tuned compression dampening options for Climbing, Trail, and Descending.

The Yeti SB-66 has a 73mm bottom bracket with splines that accept removable ISCG 03/05 chainguide mounts. The tapered head tube (44mm ID top and 56mm ID bottom) takes a zero-stack tapered headset. The rear wheel dropouts accept a standard quick-release. If you're interested in added swingarm stiffness, a 12x142mm chip kit is also available. The post-style caliper mount allows a direct fit for a 160mm rotor. It takes a direct mount top-pull front derailleur, and the top tube bears cable guides for a dropper seatpost.

The Yeti SB-66 Mountain Bike Frame is available in four sizes from Small to X-Large and in the colors Black, Lime, Turquoise, White, and Yellow.

Great all mountain bike!!!

  • Familiarity:I've put it through the wringer

I bought this bike on sale in early October after my Felt Virtue frame cracked (After 2 months, still waiting to hear back from Felt on the frame warranty by the way). I am now a proud member of the Yeti tribe. While 2 pounds heavier than my previous bike after similar build, it is hard to notice the extra weight going up and putting the rear shock on "Climb" makes a big difference. I built mine up with a Fox Float 150 mm CTD fork. This bike is super fast going down and very forgiving... No need to worry about picking your line, this bike will let you make your own line. It took a while to get used to the geometry and rake angle, and feels large and the frame is a little bulky, but hell, it is so fast and so much fun going down. In my case, with my build it came out to 29lbs, so not bad for a 6-inch travel bike. Shipping from Backcountry was outstanding, with the order being placed on a Wednesday and having the frame waiting for me when I got home from work on Friday. The only dislike is the location for the bottle cage is useless and the routing of the rear brake line requires disassembling of the rear linkage...

a little flaw

  • Familiarity:I've put it through the wringer

I got this frame two weeks ago and started building on it. When I finished almost everything and started routing cables, I found that the first cable anchor on the downtube was accidentally sealed during the welding, hence it's not usable. It would be too much hustle to disassemble all the parts I put on it (especially the headset) and return this frame, so I decided to live with this imperfection. Other than that, the frame is pretty good.

I highly recommend that everyone upon receiving of the frame check all the cable anchors.

My frame has a similar issue, not sure if it is the same anchor. The first one at the end of the down tube closest to the Bottom Bracket. Mine was not totally closed though, just smaller, I was able to use a smaller tie wrap...It could also be drilled through with a small bit...

Great bike for me

  • Familiarity:I've put it through the wringer

This is my first full-suspension bike and I love it. I wanted a bike that would be efficient enough for XC but I still wanted enough travel to be able to handle some DH. This will be my third season on it and I still have never really come across any terrain where I felt the SB was lacking. I am 5'9" with like a 31" inseam and the M fits me perfect.

Super Bike For Good Reason

  • Familiarity:I've put it through the wringer

The Yeti SB66 is a Porsche of bikes and for good reason. I have ridden mine for the last two years and the only bike that has come close to the playful nature of this bike is the HDR. What makes this bike so great is the Switch technology which resides above the bottom bracket. These eccentric circles keep you high in the travel on the climbs making the 160mm of travel feel far less and turns this bike into a pretty efficient climber. On the descents, the Switch Technology sinks you a little further into the travel which makes you feel like you are sitting in the bike and allows for greater control. This bike only gets more stable at speed and begs to be ridden hard and fast. I am 5'11'' and the medium frame fits me perfectly. Yeti's run large so be warned. If you have any questions please give me a call, I would love to talk to you about this bike.

Here is my contact information: My direct line 801.736.6396 ex. 4389. Feel free call to me anytime, I?m always happy to talk about bikes or gear or the weather. Whatever works! I?m here Mon, Tues and Friday 1:30-10pm MST and Saturday 9-5:30 as well as Sunday 10-7. I look forward to speaking with you.

Unanswered Question

Would it be possible to organise shipping of this frame to a bike shop in Ketchikan Alaska, so that I could collect the bike on my way through there via a cruise ship stop-off on 11th June 2015?

Did you raise the price of this frame? I thought it was $999 or $949 a month or two ago and was just about ready to order now.


can i use this adapter on this frame?


Hello I am from Germany. Is it possible to ship to there?

Best regards

Hi, I am in China , may you ship the frame to China ? I want a 2013 Sb66

Hi is this the right top cup for this frame? Cane Creek 40 1 1/8" ZS Upper Headset 40 ZS Tall Top 1 1/8 Threadless. Or should I get the short one 8mm not the tall one since its 15mm insert. Thanks!

What Chris king/Cane Creek Headset will fit with this frame?

hi! do you ship this frame to singapore? thanks!

Unfortunately, we cannot ship Yeti products outside of North America.

I just bought a SB66 aluminium version and my question is if I can install a RD XTR M986 or I can only use the previous model (M985)because of the hanger....

I'm trying to buy something now and I do not want to screw things up :)

PS: I bought a Shimano chip kit as well for 12x142mm, I do not know it that matters or not here....

Many thanks

i wanted to replace my 2008 frame to this Yeti SB 66 but in the recommended fork travel, it says 140mm-160mm. I currently have 100mm travel fork and it has straight tube 1 1/8. Can i still use my current fork if i buy this? Thanks.

do yeti bike frames come from the factory...
