The Test Fit RGXC Crank Arms leverage proven performance principles adopted by elite endurance cyclists. Shorter arm geometry optimises biomechanical efficiency by distributing pedal forces more evenly throughout the pedal stroke whilst enabling lower, more aerodynamic riding positions. Beyond competitive advantages, this design addresses physiological constraints, particularly beneficial for riders experiencing hip or knee mobility limitations. The result is enhanced comfort, improved power delivery consistency, and expanded accessibility for cyclists seeking mechanical solutions to positional or physical challenges.

The Test Fit RGXC Crank Arms offer a cost-effective way to try shorter crank lengths, allowing you to assess the benefits of revised crank geometry without a major financial investment. Machined from solid 7075 aluminium, they replicate the proven design and visual character of the premium titanium RGXC whilst maintaining accessibility. Though heavier than their titanium counterparts, this construction delivers genuine performance insights at a fraction of the cost, allowing you to assess how reduced arm length influences your pedalling efficiency, comfort, and positional flexibility across multiple bikes before investing in lightweight alternatives.
