Building upon the platform of the esteemed SB100, Yeti's new SB115 gets a bump in travel to--you guessed it--115mm. This is paired with a 130mm fork up front instead of the 120mm fork you'd find on the SB100. The idea is to create a bike that excels at multi-day stage races like the BC Bike Race--the types of rides where you need something more capable than a purebred XC race bike, but a hefty long-and-slack trail bike would just hold you back. The result is a short-travel shredder that climbs just as well as the SB100, but rallies the descents with greater confidence and bravado.The SB115 shares the same front and rear triangles as the SB100 but uses a revised Switch Infinity link and a longer-stroke rear shock to gain its extra travel. This means the geometry is almost identical to the SB100, with the head angle slackening ever-so-slightly from 67. 8 to 67. 6-degrees. The reach is a modest 450mm on a size large, with a 74-degree seat tube angle. On paper, these numbers might look a bit conservative, but that's right in line with the goal of this bike--to keep things lively and agile, encouraging quick accelerations and responsive handling on tight, technical racecourses. After all, when you're trying to cover ground as quickly as possible, a long, slacked-out trail bike is probably not the best tool for the job.Like their other bikes, the SB115 uses Yeti's patented Switch Infinity suspension design. The Switch Link acts as a translating pivot, providing higher anti-squat in the initial travel for class-leading pedaling performance, then moving to a suppler feel as you get deeper into the travel for excellent bump absorption and traction. This particular bike uses Yeti's C-series carbon, offering the same ride quality as their top-level TURQ frames but at a considerably lower price. This comes with a 225g weight penalty, but most riders probably wouldn't notice the difference on the trail. For good measure, the frame is backed by a lifetime warranty so you can cha.
