Yeti is expanding their range of Switch Infinity equipped bikes with the addition of the SB4.5C, a new 4.5" travel do-everything machine that's designed around 29" wheels. The fresh bike features what Yeti calls "trail-specific geometry'' - a long front end that's combined with a low bottom bracket and a relatively slack head angle - that should add up to fun machine in a lot of situations. We've spent plenty of time on Yeti's other 5" and 6" travel Switch Infinity bikes, all of which pedal like demons, so all signs point towards the shorter travel SB4.5C being able to launch like a Top Fuel drag car while being as efficient as a Prius. The new Yeti also costs nearly as much as a well used Prius, with prices starting at $5,599 USD for the SRAM GX spec'd model and going up to $10,049 USD for the no holds barred XTR and ENVE dream machine. The frame with a FOX Float DPS shock retails for $3,400 USD.

The SB4.5C frame is an all-new design for Yeti that's built around 29" wheels, and the Colorado company has tuned the bike's 114mm travel Switch Infinity suspension for a sporty feel: “The goal with the SB4.5C was to build a trail-specific bike with the firm pedalling platform and supple bump absorption that our Switch Infinity design is known for,
'' explained Chris Conroy, Yeti President. ''Based on feedback from racers on our team like Jared Graves and Richie Rude as well as a range of local riders and dealers who’ve ridden it, the SB4.5C is exactly the bike we were trying make.
'' Conroy also said that testers have been riding prototypes for over a year now, and we'd guess the bike's similar lines to its longer travel brothers made it easy to slip the SB4.5C under the radar.
The frame also sports 12 x 148mm Boost rear end, compatibility with Shimano's new E-THRU axle and a wider bottom bracket stance, and custom molded rubber guards on the underside of the down tube and on both the drive-side seat and chain stays. One thing that goes almost unnoticed is the bike's cable routing due to Yeti doing an impressive job of routing the lines inside of the down tube before they exit just ahead of the Switch Infinity unit and head back into the swing arm. This makes for one hell of a clean looking bike.
The $6,899 USD X01 model will begin shipping in mid-September, with other models following shortly after.
