Developed in collaboration with MTB legend Cam Zink, these cranks were made for the most unhinged freeride and downhill riders. Designed, engineered, and CNC-machined in San Diego, California, and tested and approved at the legendary Red Bull Rampage. Precision-machined from 7075 aluminum, these crank arms are built to take a beating and absolutely be the least of your worries in the event you decide to take your Specialized Levo 4 on course at Rampage 🙂
