The all-new Transition Spur looks ready for long rides in the backcountry and multi-day races. Find details and Transition Bikes’ launch and tech videos here…

Posted by Logan Watts

The new Transition Spur is built around 120mm of front and rear suspension and 29 x 2.4″ tires. Transition positions it as an “all-country” bike to “effortlessly explore, seek, and pursue the mountain.” With three pairs of bottle mounts on the frame, a lightweight and efficient design, and a compelling trail-worthy geometry, it looks to have a lot of potential for long days in the backcountry and multi-day rides and races. Find Transition’s launch video below, followed by frame specs, their tech video, and a full geometry chart.
