Which Tacx Thru-Axle Will Fit My Bike?

WARNING: Always follow the manual instructions to ensure that the rear axle of your bicycle is properly affixed to the trainer and that your bicycle frame is not touching the trainer housing. Failure to properly attach the bicycle to the trainer may lead to property damage or personal injury. Garmin is not responsible for any property damage or personal injury due to incorrect mounting of your bicycle to the trainer.

There are a variety of axles sizes on the market and you will need to determine the specifications of the axle on your bike. Tacx® smart trainers and wheel-on trainers only support 10/12 mm axles. We recommend that you contact the manufacturer of the bike and ask for the measurements of the rear axle. The three important pieces of information needed are:

Rear axle length
Rear axle diameter
Thread pitch

In the image below 162.5 represents the rear axle length and M10x1 represents the diameter (10) and thread pitch (1) in millimeters.
