Cam Zink Signature Crankset - 8-Bolt DM Chainring Interface

5Dev Cam Zink Signature Crankset with 8-bolt direct mount chainring interface is a purpose-built MTB crank arm set for aggressive freeride and downhill riders who prioritize impact strength, stiffness, and real clearance on technical terrain. CNC-machined in San Diego, California from 7075 aluminum and developed with Cam Zink, the arm profile and cutout architecture concentrate material where big landings demand it while trimming mass where it doesn’t add strength.

Big-hit design details that matter on trail

1. 7075 CNC-machined arms - High strength-to-weight alloy choice for riders who routinely load cranks hard on drops, compressions, and rough run-ins
2. Reinforced cutout architecture - Material is prioritized around high-stress zones for a stout feel under power and confidence on heavy impacts
3. 8-bolt direct mount chainring interface - Secure, modern mounting standard for consistent chainring alignment and straightforward swaps
4. Self-extracting hardware - Simplifies removal for service without fighting stuck crank arms
5. Low-profile arms with smoothed edges - Built for ergonomics and reduced snag risk, with shaping aimed at fewer pedal strikes in rocky freeride and DH lines
6. Spindle sold separately - 5DEV spindle required; choose the correct 5DEV spindle spec for the intended build and fit
