Meet the 5DEV Cam Zink Signature Freeride Cranks - developed in collaboration with MTB legend Cam Zink 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 arms are built to take a beating. A purpose-driven cutout architecture adds material where it counts for brutal landings and removes it where it doesn&';t for snap on the run-in. The result: stomp-worthy stiffness on par with the burliest cranks, without dead weight. PLEASE NOTE: Crank spindles are sold separately to accommodate specific individual size requirements (Cranks are only compatible with 5DEV spindles). Please note: Cranks spindles are NOT included with this product and must be purchased separately (Cranks are only compatible with 5DEV spindles) 7075 aluminum for elite stiffness-to-weight and impact resistance Designed with an optimized shape and length that features low-profile arms and smooth edges for ergonomics and fewer pedal strikes Reduced material around pedal boss for added ground clearance 8-bolt chainring interface and self-extracting hardware for easy service Item Specifications BB Included No Chainring BCD Direct Mount SRAM 8-Bolt Color Black Crank Intended Use Mountain Crank Length (mm) 150 Defined Color Black Number of Chainrings No Rings Included Pedal Spindle 9/16" 5DEV Cam Zink Signature Crankset Crankset UPC: 850076919078
