Robert Axle Project 167mm M12 x 1.75 Trainer Axle

The Trainer Axle is specifically crafted to enable compatibility between your bike’s thru axle and popular wheel-on trainers like 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo, among others. It is precisely engineered to fit your bike’s thru axle without the need for excessive spacers or extra components, delivering a streamlined, high-performance axle solution. This ensures you can train effectively, warm up properly, and stay prepared for race day throughout the season.

This Trainer Axle is engineered to connect your high-quality bike to your wheel-on trainer, compatible with major brands such as 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo, and others. Precision is our top priority, ensuring the axle fits your bike as well or better than the original thru axle. Installation requires only a standard 5 mm hex/allen key—the same tool you carry on every ride. When it’s time to race or ride outdoors, simply remove the bike from the trainer, detach the drive side axle end, and you’re ready. Designed for both indoor and outdoor use, this axle offers seamless versatility.

Important: Before you order, make sure your specific trainer will accommodate the width of your modern thru-axle equipped bike. Measure your trainer at the widest setting and measure the outside width of your bike frame. The trainer axle ends will extend 15 mm past your frame on each side.
