Overview & Features
The SuperB 275 titanium mountain bike frame is not just an XC on smaller wheels. The complete design is aimed at smaller and lighter riders, or simply someone who wants to utilize the smaller 27.5″ wheel size. Plainly, it’s the purest racer in our SuperB series lineup. The rear triangle accommodates the narrower cross country tire width (up to 2.4) rather than plus-size tires. In addition, the SuperB 275 optimizes short 100mm travel suspension forks. It’s also fun on a rigid fork with an approximate 490mm axle to crown.
The SuperB 275 is a compact and minimalist design built with material weight in mind. It’s fabricated with smaller frame tube sizes, and as a result, it’s the lightest of the SuperB group! Therefore, we recommend the X-Small through Medium frame sizes have a rider weight limit of 175 pounds. However, there is no limit on the Large and X-Large frames.
Not only is pedaling efficiency maximized through the geometry and shorter fork travel, but also, the 27.5″ wheel size optimizes acceleration without sacrificing rolling speed. And, as a result, the lightweight SuperB 275 has proven itself to be a podium machine! Multiple highly competitive athletes have race wins and Top 5 season finishes on it. If you want the lightest and quickest bike for XC racing, or just plain fun, this is it!
