Built for gravity riders who demand both performance and flair, the Truvativ Descendant CoLab Troy Lee Designs crankset pairs a proven downhill-ready platform with eye-catching TLD graphics. Designed specifically for slack-geometry downhill bikes, the short 165mm crank arms clear obstacles and keep pedals off the ground through rough terrain.
