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.

Here's what others have to say...

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

HI Walter,

The new Shimano Direct-mount derailleurs like the RD-M986 should include a link that makes them backwards-compatible with traditional-mount frames like the SB-66.

what are the shipping dimensions and weight of this frame?

Responded on


This frame ships in a box measuring 42x8x23 inches. A medium frame in the box weighs about 17 pounds.

Give us a call or chat if you have other questions about the SB-66, or to place an order!

It is on the lighter end of what will work with this frame, but your fork is within the range of what the SB-66 was dexsigned to work with. Build it up and go have fun!

what options do I have if I want to put a DT swiss or Mavic rear axle 12x142?
From what I read here the chip kit only works with shimano axle....which sounds kinda stupid, but anyway....

Thank you

Responded on

The 2013 SB66 would need the Yeti Chip kit, YTI0108, to run a 12x142 axle. It does require the use of Shimano's 12x142 axle.

Responded on

The Shimano axle will work with DT and Mavic wheels. The Shimano nut just sits outside the frame, whereas DT 12mm axles are paired with frames that have the threading molded into it.

Thanks man, real help! I have everything now!

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.

Best Answer Responded on

You'll want to get a new fork , you don't want to ride a frame designed for 140mm-160mm travel with a 100mm fork.

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.

Most likely you'd be a small unless you have unusually body proportions such as arm or leg length. Your best bet is to check our fit calculator at the bottom of the page and imput all your measurements.

hello, this frame has the chain guide, is the SB66 or SB66 comp?

Best Answer Responded on

This is the SB66 frame. The Comp frame is the same frame, but with the non Kashima coated EVO rear shock. Neither frame includes a chain guard. Yeti uses a separate removable ISCG mount that slides onto the BB shell, item YTI0130.

Responded on

Im pretty sure its the comp. The SB66 has a carbon rear triangle and the comp is all aluminum. The Comp also weighs in at 7.75 where as the sb66 comes in at 6.8 pounds.
