Yeti just dropped in on their slackest mountain bike ever – the new 165mm full carbon enduro SB165 with their unique Switch Infinity sliding main pivot and a coil-specific suspension design. Developed with multi-time EWS champ Richie Rude, the new SB165 was developed to build a playful trail bike without any limitations – built DH tough with Yeti’s lifetime warranty to back it up.

Yeti built the new SB165 as the “slackest sled” in their line-up to match DH bike descending to trail bike climbing –  a bike built “for steep descents and technical, big consequence riding”.

The heart of the bike is the Switch Infinity sliding main pivot, scaled up for 165mm of enduro rear wheel travel.

Geometry

Not just slack for marketing’s sake, this new 63.5° headtube SB185 is really meant to shred super steep & technical trails. But the efficient pedaling of the Switch Infinity system and a steep 77° seat angle (plus short offset forks) means the bike still climbs well, giving it progressive trail geometry to create an all-rounder all-mountain trail bike that doesn’t need a shuttle to the trailhead.

The SB165 gets 165mm of rear wheel travel from the new carbon frame, paired to a significantly longer 180mm fork to balance the bottomless ride feel. Two levels of carbon are available, Yeti’s lightest top Turq series layup or the C-series that adds about 220g while retaining the same strength & stiffness at a fraction of the cost.

The bike was developed around coil shocks, with all new suspension kinematics to marry the best of supple coil chock feel & the efficiency of the Switch Infinity platform

By doubling the shock ratio for the SB165, Yeti says the new bike keeps the same supple feel & while retaining the anti-squat performance of the shorter air shock bikes.

Plus, the Switch Infinity system let them create their most progressive kinematics yet to get the most out of linear spring coil or modern high-volume air shocks. According to Yeti Director of Engineering, Peter Zawistowski, “In layman’s terms, it climbs great (even for a big bike) and crushes the downhills.”

Yeti stuck with 27.5″ wheels for the new long-travel bike to keep the playful nature of the new bike. This isn’t meant to be a DH racing rocket on a straight race course, but a big, versatile trail bike to shred the most technical terrain.

The SB165 (as are all 2019 & newer Yeti bikes) is covered by Yeti’s “no-B.S. Lifetime Warranty”. Ride it like the gravity sled it is, and if something goes wrong Yeti will make it right. Just register your bike, first. They even do a discounted crash replacement program too it you accidentally smash it into a wall. “You CAN race, jump, ford streams, shred the gnar or ride it hard. Don’t worry, you don’t need a lawyer to decipher how it works.

  1. Hello Yeti!

    I’m looking for a new bike. Definitely going 29er! The 130 looks amazing!

    Couple questions about the warranty v crash replacement. Sounded like the replacement was “no questiones asked” which seems to be a normal thing for “fancy carbon things” these days. Given the well-deserved status and marketing by Yeti I am surprised to read the folloeing line about a discounted crash replacement. What’s the difference? The way my local shop manages the paperwork? Unfortunate

    Owners, I think, would really appreciate the explanation between breaking a bike while riding and, I guess, smash it into a wall. All hyperbole aside.

    I have had a few carbon bikes that have broken on minor things, and I have also almost died on crazy crashes on the most boring trails while the bike was only scratched. Sometimes the bikes are warrantied under a guaranteed ridership program of sorts, and sometimes I have paid many hundreds of dollars for a swingarm I rubbed on a boulder in a rock garden I have traversed fifty, or more, times. One of them was a Yeti frame. I was given a free swingarm on a SB6 because of a known issue. A thing of the past.

    Anyways, I just wish more brands would not be ambiguous with their warranty/replacement program. Seems easy enough to do, but what do I know.

    Thanks for your time!

    BTW your 29ers are on par with the best,

    Zach
