Yeti SB6 carbon switch infinity (2)

In the past few months, it was hard for Yeti to keep the new SB6c under wraps. After all, the bike was raced twice in the Enduro World Series by Jared Graves, and both times Jared and the new bike were on the top step of the podium.

“The SB6c was built as a pure enduro machine and proved it’s mettle before it went into production by winning two consecutive rounds of the Enduro World Series.” said Yeti President and co-owner Chris Conroy. “Long-time Team Yeti rider, Jared Graves, was critical in designing this bike. He worked with our engineers to create the ideal leverage curve and was instrumental in nailing the geometry which is long, slack (65.5° head angle) and low.”

After the stealthy prototype made its way around the internet, today Yeti made the SB6c official making it the second bike to use Switch Infinity. As the bigger brother of the SB5c, the Enduro proven SB6c looks ready for prime time…

At the heart of the SB6c is the new Switch Infinity system. Co-Developed with Fox, the design is the evolution of the Switch suspension system but instead of a concentric axle, uses a bushing that rides on two Kashima coated shafts. As you sit on the bike the linkage moves up on the sliders, and then reverses direction when going through the travel in effect creating an infinite link. Combined with a carbon dog bone link and a carbon frame, weight is kept to a minimum offering a suspension platform that can handle something like the EWS with its 160mm of travel front and 157mm rear, but still allow you to pedal to the top.

At this point, most Enduro bike standards seem to be worked out with a 142x12mm rear axle, 27.5″ wheels, tapered head tube, stealth dropper routing and really the only wild card these days – a pressfit 86 bottom bracket. Complete bikes will be sold with the X01 build kit as shown above starting October 1, with framesets available later this year. The X01 build will get you a Fox 36 and Fox Float X shock for $7399 (does not include ENVE wheels). This particular bike with XTR pedals installed weighed in at 29.1lbs, but Conroy told us that the show bike had 6 coats of paint. Conroy’s personal bike was built out to about 27 lbs with a custom build.

In addition to the neon green, the SB6c will also be offered in Yeti’s more traditional turquoise and matte black.

    Man, there is even more going on there with that design than the various iterations of GT’s wonky iDrive, though to be fair, it’s a LOT more tidy. Fascinating suspension design, really!

    And I too am a total sucker for Yeti turquoise, but it would take an awful lot for me to give up my Tallboy C. I’d love to ride the 29er version to compare to the VPP. Really, really nice job, Yeti!

    Finally! I’ve been waiting for a 27.5 version of the SB-66.

    Any idea when the full geometry specs will be available? I’m interested in the details.

    One question: Will the PF86 BB work with 30mm spindle cranks? I just bought new Race Face Next Cinch cranks that use the 30mm BSA bottom bracket (for threaded BBs). I don’t want to swap them, as they are absolutely awesome.

    The service intervals for Fox suspension units require that the shafts/stanchions be wiped down with a damp cloth after every ride. Getting a damp cloth around those ‘Switch Infinity’ shafts doesn’t look like much fun.

    I don’t think Yeti can make up its mind on what to do. They seem to have more iterations of suspension design than most other companies. I have an aluminum sb66 from 2012 which rode well, although a bit heavy. They suddenly just quit making the bike two years later! Switched to a carbon a Tallboy LT, which blows it away in almost all aspects. You don’t see Santa Cruz doing this, they stick with what they believe works. This thing looks so complicated and high maintainance, I don’t expect it to last. The suspension shocks will get ground down by dirt on long dirty/wet rides, common with enduro riding. But no worry, by then Yeti will have another design. Are we there Yet(!).
