Our Trainer Axle is designed to adapt your thru-axle equipped bike to on-wheel trainers, such as a 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo, and many others. Our goal is to fit the thru-axle to your bike perfectly to minimize spacers and extra parts, providing a clean, high-performance axle for your bike. Train, warm up, and be race ready and fit for the season.
This axle will replace the R.A.T. axle found on all Cervelo R.A.T. equipped bikes. In addition to this axle, we include our replacement derailleur hanger with traditional threads. This axle combined with the replacement derailleur hanger will provide a complete threaded thru-axle system. Our derailleur hanger matches the geometry and construction of the stock derailleur hanger in every way for crisp shifting performance.

- No special tools required. Design allows for wheel installation or removal using your standard 5mm hex wrench.
- Designed, built, and quality tested in the USA. Proven around the world.
