AV3 Crank Arms

5Dev AV3 Crank Arms are signature MTB crank arms built around Asa Vermette’s preference for confident bike control when pinching the arms—ideal for riders who want a high-grip interface and a clean, modern drivetrain setup. CNC machined from forged 7050 aluminum, the AV3 delivers the look and precision expected from 5Dev while using a forged starting point to bring cost down compared to the billet R-Spec line.

What matters on the trail and in the park

1. Forged 7050 aluminum + CNC finish - Targets high strength-to-weight and impact durability with tight machining tolerances
2. Asa Vermette signature knurled arm face - Adds tactile grip for riders who pinch the crank arms for control during tricks, compressions, and high-movement riding
3. SRAM 8-bolt direct-mount chainring interface - Fits the widely used 8-bolt standard for straightforward chainring compatibility and swaps
4. Cost-conscious 5Dev construction - Forged blank machining reduces cost versus 5Dev’s billet R-Spec line while keeping the same purpose-built approach
5. Claimed weight - 645g per arm
