When every second counts, you need to be able to rely on your bike to deliver seamless gear shifting, reliable braking and explosive acceleration, every time. That's why we developed the Reaction GTC One Di2 29, which uses Shimano's flawless Di2 technology to perfectly match man and machine in the quest for ultimate performance.

Frame: No compromise: that was the brief we gave to our design and engineering team. And boy, did they deliver. Twin Mould technology creates the ultimate combination of low weight, incredible efficiency and unbelievable comfort. We know which tweaks count: X12 dropouts enhance stiffness, while a 27.2mm seatpost improves comfort. And, of course, our acclaimed Agile Ride Geometry means you get all the benefits of easy-rolling big wheels, but with ride-by-wire handling.

Features: Highlight of the Reaction GTC One Di2's component list is, of course, Shimano's Di2 XT transmission. The 2x11 setup of of 26/26 chainrings driving an 11-42 tooth cassette is well known, but combined with electronic control it's an unbeatable combination of precision and reliability. Simply put, you can concentrate on getting the power down... and the Reaction GTC One Di2 won't waste a single second in transferring it to the trail. Combined with the plush trail-taming performance of Rock Shox's Reba RL and light, stiff and strong Fulcrum Red 66 wheels shod with Racing Ralph and Rocket Ron, there's nothing stopping you from reaching the podium.
