5DEV Road / Gravel / XC Test Fit Crank

5DEV Road / Gravel / XC Test Fit Crank Info

5DEV Road / Gravel / XC Test Fit Crank was created for riders who want to experiment with shorter crank lengths before committing to a full titanium upgrade. As shorter cranks gain traction among elite road, gravel, and XC riders, many are discovering improvements in pedaling smoothness, aerodynamic positioning, and joint comfort—especially for those managing hip or knee mobility limitations.

The Test Fit Crank mirrors the geometry and aesthetic of 5DEV’s RGXC Titanium cranks, but is machined from a solid block of 7075 aluminum. The result is a durable, functional platform designed specifically for evaluation and fit testing. While heavier than its titanium counterpart, it offers a low-risk way to experience how shorter cranks can change ride feel, comfort, and performance.

Designed to work with SRAM’s 8-bolt interface, the Test Fit Crank allows riders to test fit and function across road, gravel, and XC setups. Each purchase includes a $100 discount code toward a future set of RGXC Titanium Cranks, making it a practical step in dialing in your ideal crank length.
