The Robert Axle Project Trainer Axle

Our 12mm Thru Axles for bike 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, you’ll have a high performance thru axle, already installed. No need to switch axles all the time. Your bike is always ready to ride, indoors or out, with or without the trainer. Eliminate excuses that could stop you from riding, by never needing to swap axles again.

Please Confirm the Length of the Axle you are replacing or the Frame Spacing.
