5DEV R-SPEC Trail Enduro Cranks represent the top tier of 5DEV’s crank lineup—engineered to exceed conventional standards for strength, precision, and race-level performance. The R-SPEC designation isn’t cosmetic; it reflects a design and testing process informed by elite-level racing across downhill, enduro, and gravity disciplines worldwide.

Machined from 7050 billet aluminum in San Diego, California, these cranks are built to handle the sustained loads, impacts, and torque demands of modern trail and enduro riding. From bike park laps to full-length enduro stages, the R-SPEC Trail Enduro Cranks deliver a stiff, composed ride feel with the durability required for aggressive use.
