A higher level.

Roll up to the trailhead and unleash the hungry Yeti SB66 Enduro Mountain Bike. Equally happy half-wheeling racer-boy hardtails on climbs or outgunning portly freeride sleds on technical descents, the SB66 takes all-mountain riding to its highest form, thanks to the ride-optimizing eccentric lower pivot.

  • Switch Technology uses an eccentric mechanism that continuously adjusts the lower pivot position for the perfect balance of pedaling efficiency and plushness
  • A rearward axle path at the beginning of the stroke lets the wheel roll over small bumps while maintaining a firm platform
  • At 100 millimeters into the travel, the link rotates in the opposite direction for a responsive midstroke, and finally to the end position where the suspension is independent of chain forces to avoid any feedback or spikes
  • A compact link assembly is located inside a single forged housing, and mated to a stiff rear end using oversized pins to provide wallow-free, pinpoint handling
  • Kashima-coated Fox 32 with thru-axle and Float RP23 offer a wide range of adjustments for optimum control and performance in varying conditions
  • SRAM drivetrain features a budget-friendly mix of X7 and X9 components for fast and precise shifting
  • Powerful Avid Elixir 5 brakes haul the SB66 down from speed with ease and traction-optimizing modulation

Love SB66, should be cheaper since made in Taiwan

This is my 3rd mountain bike in 5 years living in CO and it took me to the next level in 3 weeks! I demoed a $4K specialized bike before SB66 and SB66 beat it hands down. I also rode Yeti 575 and while being a great bike, it was not as impressive as SB66, esp climbing uphill, so believe the hype!
My previous bikes were within $1000 range and just pulled me out of the house on occasion, but Yeti made me a more skilled rider and now I am hooked on mountain biking. SB66 took about 3-4 rides to dial in suspension settings, and now it shines and keeps grin on my face. I went from newbie to the next level in just a few weeks with this bike! I mostly ride mid to mid-high level technical trails in CO front range area., right where Yeti is being developed and tested, so this may have contributed to the brand success.

My beef with Yeti is that starting this year model (2011) you only get 2 years of warranty on frame instead of 5 years as they did before. This is important with new frame on this bike, which no one knows how long it will last with pivot. Frames are no longer made in CO, but in Taiwan, so should we get a discount? But I will keep my fingers crossed and enjoy this bike in the mean time.

Anybody know if yeti sells dropouts for a 12x145 yet?

yes they do, just not here yet. looks like you'll have to hit up your local dealer(if you have one) for the chip system or iscg mounts.

Great Bike, just give yourself some time for the correct setup.

Hi there, after 3 weeks with the yeti sb-66 I just want to say that is without a doubt one of the best bikes I eve own. I have to make it clear, I don’t do XC racing, or really Hard All DH, I’m just a dude that wants to have fun with the bike in all kind of rides (long distance trips , uphill, downhill, xc tracks, mountain trails and even in the road).
So in these 3 weeks I have enough time to test the bike in all kind of terrain and had a really smooth ride in all tested conditions:
• In the Road??? Just put the RP23 in the firm option, block your front suspension and Buala!!!, not the fastest bike on earth, but a really firm ride with not too much weight for an all mountain bike.
• Downhill in trails with rock gardens??? The Yeti Sb-66 will gives you a really good grip and no vibrations at all, so If you are like me, a 30+ year Pal, you will really enjoy that there will not be pain in your back for vibrations or head neck injuries after a long downhill. Plus you have 6 inches of travel !!! go and get all the jumps, you can!!!
• Uphill with rock gardens or really technical stuff??? No problem either, the suspension will help you to do the job, great grip just like a goat. And what to say about the 10 speed cog?? The 1-10 gear relationship will make every hill a pancake to eat.

What about suspension travel ??? Well here I have to say that maybe a little aggressive fork and shock will make a better downhill ride, if you like to do serious downhill ,add an aggressive fork and shock, but again this is a bike for all around the mountain not for an only one specific task.
Just one more advice, I enjoyed bike not in the first week, not in the second it was until the 3 week when I give like 8 hrs to correctly setup the seat post height, handlebar height and SUSPENSION that the bike comes alive and make and outstanding piece of technology, don’t do this homework and you will have just a ‘nice’ bike, so invert really good time to make the bike shine.
Just one more thing, I’m not a rocket scientist and either know the technology behind the suspension of the bike, just as a regular pal I can say in resume: “This bike is a piece of art, climbs really better than my Stumpjumper 07 and go down faster as my XR250 Honda :D does, but again, that just will happen when you get serious about setting up the suspension”.


P.S .And the color ROCKS https://picasaweb.google.com/112897219932664081383/YetiSb66#slideshow/5664674852593692418

Yeti SB-66 is the stuff

Just got done with my first ride on this bike. Bike was set up as shown here except with some XO shifters and some lighter bar/stem/post goodies. The suspension isn't 100% dialed in yet, but even at 80% there this bike climbs like a champ and eats up anything you can find going down. Today I rode lift-accessed DH, a DS-style "flow" track, a terrain park with some 5-6 foot drops, and then did a 3 mile climb followed by a long descent on singletrack. The Yeti did everything very well. I come from an XC background so it was a bit of a revelation to have that much squish on the down, but I didn't pay for it at all on the up. The slack head tube means that this can run very fast on DH oriented days, but the suspension works! Believe the hype - I'm a Yeti devotee and my previous bike was a 575 and this honestly blows that bike out of the water so long as you're willing to push the bike pretty hard.

Responded on

Mark what do you think about the long length of the top tub? how tall are you and inseam? what size did you get? I'm really torn being that i'm 5'11 i'm right in the m/l range. My current bike is a 18 and has always felt small so i'm a little nervous about going to the m. any advice would be appreciated. I've road (around the store parking lot) a large 575 and liked the length but this is a tad longer.

Responded on

The top tube length was a plus for me as I'm also 5'11" with a 30 inch inseam and I was previously on a Large 575. This fits better and allows me to size down without being scrunched up.

Responded on

Mark, what kind of paperwork/accesories came with your bike? Did it come with an air shock pump for tuning?

Responded on

I am also 5'11" with a 30 inch inseam and I got the medium. I previously rode a large 575 and it was a touch big on me but manageable. I could get away with the large but I like the smaller frame for more fun on the way down. If I had a 32" inseam I might go Large.
