If you follow Yeti's colorful history from the mountain-dominating FRO hardtails, to the gravity-defying Lawwill-suspended DH-8, to the category-shattering 575, you'll notice Yeti has constantly pushed the limits of bike and suspension design -- and the SB66 Race X0/X9 Mountain Bike is no different. Showing up to the mountain bike pill party with a mind-blowing eccentric lower pivot, the SB66 mixes pedaling efficiency with an ultra-stiff, long-travel chassis for trail-dominating performance. Take your mountain adventures to the next level when you throw a leg over the Yeti SB66 Race X0/X9 Mountain Bike.

  • 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 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. Then, in the end position,the suspension is independent of chain forces to avoid any feedback or spikes
  • Compact link assembly is located inside a single forged housing, and mated with oversized pins to a stiff rear triangle 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
  • 2x10 SRAM drivetrain featuring a smart mix of X.9 and X.0 components offers fast and precise shifting between power-optimizing gear ratios
  • Powerful Avid Elixir CR brakes haul the SB66 down from speed with ease and traction-optimizing modulation
  • US Yeti dealers are prohibited from shipping Yeti bicycles to any country other than Canada, Mexico or the US.

I love this bike

    I've been riding it pretty hard these season and haven't had any problems. It climbs pretty well, but that's not its strength - this bike really loves going downhill. Handles great around turns at speed. Handles drops well and the 6" travel makes technical spots almost too easy. The ProPedal and front shock lockout really help with climbing.

    Love the SRAM drivetrain, I love being able to shift five gears down with a single button push when I come up on an unexpected hill.

    Haven't gotten around to convert to tubeless yet, though I plan to. I may as well, since the tires are very difficult to get off the stock wheels (trust me, you *don't* want to have a flat on the trail with the stock setup.)

    This is an ideal bike for Moab and the Wasatch Mountains, where I do most of my riding. It's flexible enough to be a XC rig but it's beefy enough to handle some FR stuff as well. It could probably handle a lot of Vancouver's North Shore trails and Squamish as well. I don't think I'll be taking it to the Whistler Bike Park, though.

    iam interested in the sb66 xo/x9 can i get this bike with a 3 chainring crankset


    awsome bike

      I am coming from 2006 Yeti 575 and this was major upgrade for my climbing abilities and no reduction on the dh at all if not the opposite. When I got the SB I was locking the rear shock on climbs following my old habits when one day at the top of the trail I realized that I forgot to lock it and I actually didn't even feel it. Now I don't bother and I find it more efficient on loose terrain. I was a bit concern with the SRAM build since everyone was back ordered on the XT but I loved it on the fist ride. The 2x10 is great and I would never go back. The brakes are great with nice modulation and I love the adjustability. So far no problems. Excellent buy.

      Note: I had to adjust my chain length and reduce it by about 5 links. I think they might have sized them for 44 ring and the sram comes with 39.

      i ride trails out in AZ but its on a heavy all mountain rig and its hard to push up trails hear in 100 degree weather but i am looking to buy a aggressive light trail bike. would this be the one for me?

      One of the best! The SB can really handle everything, and is very well suited for the riding here in UT/AZ.

      the yeti sb-66 is a freaking mountain goat it climbs with ease and begs to be pointed down hill . fantastic quality well built bike would recomend to anyone who wants a fast all round bike

      What would be the possibility to upgrading...

      What would be the possibility to upgrading to a Talas 32 or 36 front fork and what would be the additional cost to do this?

      best way to get an answer is to call our customer support

      I discussed this with customer service and they indicated that there is no "swap" but that you'd have to buy the Talas 32 or 36 and they would install it for you. You would keep the stock fork from Yeti.

      I have ridden the bike in both configurations and believe it or not I like the 32 fork over the 36. It keeps the front end light and responsive. The bike was way more fun to ride that just plowing with the 36. It was easier to get air, and I felt like the 32 in no way compromised plushness.
