The Robert Axle Project 12mm Thru Axles for Trainers adapt your 12mm thru-axle equipped mountain, cross, gravel or road bike to modern bike trainers. No longer do you need a second bike for indoor training or warming up for a race. With our 12 mm Thru Axles for Trainers, you can now train and warm-up on your race bike. The best part? When it’s time for your race or time to head outside, simply remove the drive side axle end from the Robert Axle. You’ll have a high performance, low profile axle for racing. When you are ready to sit on the trainer again, put the end back on and use your bike on the trainer.
This Trainer axle is designed to adapt your high quality bike to your trainer. These are compatible with all the popular brands: 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and more.
Our first priority is building a precision thru-axle. Our axles fit into your bike as well or better than the stock thru axle.
The axle is installed with a simple 5mm hex/allen key. The same tool that you carry on every ride.
The best part? When it’s time for your race or time to head outside, simply remove your bike from the trainer and go. Our axle is suitable for use on or off the trainer. Indoors or out.
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. Our axle-ends will extend 15mm past your frame on each side.
