- An inexpensive way to try short cranks before making the big commitment - Test Fit Cranks are the same geometry as the RGXC Ti Cranks but made from a solid block of aluminum - Not light but a low-risk way to see how a short crank might improve ride quality, comfort, and performance. Great for a shop setting where multiple customers might try - Spindle can be swapped to fit different bikes and needs - Aluminum is not anodized so these cranks will tarnish with long term use - Features 8-bolt chainring interface - Weight: 660g
