A Smarter Setup
For many years cycling was a sport both proud of and held back by tradition. As more scientific methods were applied to training and bike design, performance and rider comfort were greatly enhanced. Dupli-Fit extends that scientific approach to upgrading how we capture and duplicate bike setup.
Don’t Get Bent!
The near universal use of disk brakes has
been a great benefit to safety and riding pleasure. Rotor Protect ensures that you won’t be stuck with a bent rotor anytime you remove wheels for travel or service. Its compact size and easy one-hand installation ensures it’s use.

Used Dupli-Fit on my road and gravel bikes that I thought I’d setup identically but they were off. This tool is more accurate and faster as well. Thanks.

Thanks, Dave. I travel with my bike a lot and this will really make me feel better now. Always so worried I would arrive someplace and the rotors are messed up. Thank you
