Robert Axle Project Turbo Trainer 12mm Thru-Axle - M12 x 1.75 - 170mm

Please note: When selecting the correct axle for your bike there is a handy Thru Axle Finder so you can easily find the exact axle you need. This can be found by scrolling down the page to the downloads section or by visiting the Robert Axle brand page on our website. If you are still unsure then please contact us before purchase.

The Robert Axle Project Trainer Axle is designed to adapt your thru axle equipped bike with your wheel-on trainer, such as a 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other trainers. Their goal is to fit the thru axle to your bike perfectly, so we 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.

Cervelo owners with RAT thru axles: This axle will replace the RAT axle found on all of their RAT equipped bikes. In addition to this axle you will need to replace the RAT compatible derailleur hanger with Cervelo threaded hanger Part Code: DRH-WMN112. This axle combined with the replacement derailleur hanger will provide a complete threaded thru axle system. If you don’t know what “RAT” is then this message is not for you, but the axle still is.

- Primary focus is to build a precision thru-axle. RAP say that their axles fit the specific bike as well or better than the stock axle.
- Suitable for on or off the trainer. Indoors or out. Ride/Train more, with less time wrenching.

- Designed, built & quality tested in the USA.
