Product Details
If you want to fit your bike to a Tacx trainer and the rear wheel is solid axle, not QR (quick release), replace the original track nuts (the ones that secure the wheel to the bike frame's rear dropouts) with Tacx Axle Nuts.
Why? Because the trainer's clamp is designed to be secured to the rounded dome shape of a QR, which Tacx Axle Nuts perfectly replicate.
- Tacx Axle Nuts fit 10mm diameter rear axles - the most common size.
