Description

Switching it up.

The alloy SB-66 marked a change in direction for the boys in Golden, CO, as it was the first platform to receive Yeti's innovative approach to suspension design -- Switch Technology. Developed to both climb and descend aggressive backcountry trails, the 152mm travel SB-66 Mountain Bike Frame represents the current direction of progressive mountain biking.

Key to the SB-66's multifaceted ability is its distinctive Switch Technology, rear suspension design. Technically, it's a mini dual-link system. And while there're a number of iterations currently on the market, Yeti's application offers something a bit different. Switch Technology refers to the rotational movement of an eccentric housed in the lower pivot.

Essentially it's a pivot within a pivot, with 12mm separating the centers. As the rear suspension compresses into its travel, the eccentric (and the pivot) rotate 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.

When riding, it feels as if the SB-66 has a built-in pedaling platform, and since it's a result of the eccentric, it doesn't rely on heavy compression damping. This gives the SB excellent traction and control on choppy trails. At the same time, the SB-66 is ready for larger hits. Once the mid-stroke is exceeded, Switch Technology changes direction and rotates clockwise. This keeps chainstay growth at a minimum for a reduced pedal kickback and lively handling on tight and twisty trails. It also ramps up the leverage ratio. For the most part, Switch Technology produces a flat curve, but once the rear suspension is pushed towards the limit, it firms up to provide a bottomless feel.

There's another benefit as well. Since the bottom bracket, eccentric, and lower pivot for the swing link are all machined into a single, forged aluminum structure, they're in perfect alignment on every bike. 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.

Each of the SB-66's 6061-T6 frame tubes are shaped for a purpose. Take the seatstays for example -- they flare in the vertical plane towards the dropouts. On the left side, this helps distribute loads from the post mount. Otherwise, the larger cross-section handles compression loads without flexing. The down tube is ovalized at the bottom bracket to enhance stiffness, and it bears flattened sides to channel and distribute stress from the shock mount.

Attached to that shock mount is a FOX FLOAT CTD shock with the Kashima coating. Since Yeti partners with FOX for its World Cup team, it's no surprise that they spec the latest from FOX. The Kashima Coat creates a slicker, more durable finish on the shock shaft, allowing the suspension to respond to bump input with greater sensitivity. The dampening system has been revised with a simplified user experience as the main objective. 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. Out back, it comes equipped with chip-style dropouts that 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...

Hi,
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

Walter

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

HI,

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
Walter

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!
Cheers

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.

Best Answer Responded on

The head tube is faced before leaving Yeti's factory, our shop also quality control checks every frame/bike before shipping.

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.
