The Reaction C:62 Rookie is built to take that enthusiasm, and turn it into trail-devouring speed. Crafted from the same premium C:62 carbon as our adult race bikes, it boasts exactly the same features you'd expect to see on a World Cup athlete's bike. The Manitou Markhor suspension fork is specially tuned for a child's lower weight, for the best possible performance. Sram's NX Eagle 1x12 gears deliver a huge range and precise shifts. And Magura MT Thirty hydraulic disc brakes have all the power needed to bring the tough Answer Atac AM wheels to a halt.
