It's no secret that World Tour GC contenders have been making the switch to shorter crank arms - and not just for marginal gains. Shorter cranks help smooth power balance, allow a lower, more aerodynamic position, and can be a complete game-changer for riders with hip or knee mobility issues.
If you've ever thought about changing crank lengths, cost is probably the first thing that comes to mind - especially if you've got more than one bike. That's why we made the Test Fit Crank. Same geometry and aesthetic as the RGXC Titanium, just made from a solid block of 7075 aluminium. They're not light - but it’s a low-risk way to see how a short crank might improve ride quality, comfort and performance for you.
