B-Side v.3 (27.5″ / 650b)

27.5" (or 650b) is the tire size halfway inbetween the more common 26" and 29" MTB tires. 650b tires roll over obstacles better and are more stable at speed than a 26" wheel and are lighter weight than 29er wheels. 27.5" bikes also have less of the unwieldy feel some riders feel 29ers have. Our 3rd generation B-Side has a slightly slacker geometry. Still great for XC trail riding, but more controllable when things get fast. Snazzy Tange/IRD Sliding Dropouts allow you to go single-speed or geared.
