Robert Axle Project Trainer Axle M12 x 1.0, 154/160/167mm

The Trainer Axle by Robert Axle Project is engineered to seamlessly connect your thru-axle bike to wheel-on trainers like 1up, Blackburn, Cyclops, Kinetic, Tacx, and Wahoo. Precision designed to fit your bike with minimal spacers and components, this axle offers a streamlined, high-performance solution. It ensures efficient training, optimal warm-ups, and readiness for racing seasons.

This Trainer Axle is crafted to connect your premium bike to wheel-on trainers effortlessly. It is compatible with leading brands such as 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo, and others.

Our top focus is crafting a precision thru-axle that fits your bike as securely, if not better, than the original. Installation requires only a standard 5 mm hex/allen key—the essential tool you carry on every ride. When it’s time to race or ride outdoors, simply detach your bike from the trainer, remove the drive-side axle end, and you're ready to go. This axle is designed for seamless use both on the trainer and on the road.

Important: Prior to ordering, verify that your trainer can accommodate the width of your thru-axle equipped bike. Measure your trainer at its widest adjustment and compare it to the outside width of your bike frame. Note that the trainer axle ends will extend 15 mm beyond the frame on each side.
