12mm through axles for trainers
Our 12mm trainer thru axles adapt your 12mm thru axle equipped mountain, cross, gravel or road bike to modern bike trainers. You no longer need a second bike for indoor training or warming up for a race. With our 12mm trainer thru axles, you can now train and warm up on your racing bike.
The best part? When it's time for your race or to go out, you'll have a high-performance thru-axle. No need to change axles all the time. Your bike is always ready to ride, indoors or outdoors, with or without the trainer.
designed to fit your bike
12mm trainer thru axles are unique because they are specifically designed to fit your specific bike using minimal washers and spacers. Unlike common trainer thru axles for fitting studios, Robert axles are lower profile and can be used on or off the trainer.
- Precision engineered and machined to fit the specific bike as well or better than the stock axle.
- Suitable for use with or without the trainer. Indoors or outdoors.
- No special tools required. Easy installation using a standard 5mm hex key found on your multi-tool.
- Designed, manufactured and quality tested in Bend, Oregon, USA.
