Rotor 3D24 Track Bike Chainset 144 x 5 BCD
Red lights, stop signs, blind intersection, and clueless drivers constantly test your fast-twitch muscles — you need your bike to respond as fast as you do. Track cycling also demands a lot of hard, high power efforts so stiffness matters to help maximize your output — you need cranks that respond to a blast of power that will instantly launch you in a sprint. The 100% CNC-machined 3D24 TRACK has been specially crafted with a shorter axle and 144BCD specific to track and fixed-gear bikes. The 3D24 track crank continues to lead the 24mm track crankset market in terms of technology and performance.
