Trainer Axles

Our 12mm Thru Axles for Trainers are unique because they are designed to fit on your specific bike using minimal washers and spacers. Unlike trainer thru axles common for fit studios, the Robert Axles are lower profile and can be used on or off the trainer.

• This Trainer Axle is designed to adapt your favorite bike to your wheel-on trainer. Our axles are compatible with all the popular brands: Blackburn, Bkool, Cyclops, Elite, Kinetic, Tacx, Wahoo, and more.
• Our first priority is building a precision thru-axle. Our axles are precision designed and machined to fit into your bike as well or better than the stock thru axle.
• The axle is installed with a simple 5 mm 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, remove the drive side axle end and go. Our axle is suitable for use on or off the trainer. Indoors or out.
• Designed, built and quality tested in Bend, Oregon, USA.
