Our goal is to fit the thru axle to your bike perfectly, so we minimize spacers and extra parts, providing a clean, high performance axle for your bike.

Description

  • This Trainer Axle is designed to adapt your Surly bike to your wheel-on trainer. These are compatible with all the popular brands: 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and more.
  • Our first priority is building a precision thru-axle. Our axles 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 and go. Our axle is suitable for use on or off the trainer. Indoors or out.
  • Important: Before you order, make sure your specific trainer will accommodate the width of your modern thru-axle equipped bike. Measure your trainer at the widest setting and measure the outside width of your bike frame. The trainer axle ends will extend 15 mm past your frame on each side.

    Our Trainer Axle is designed to adapt your thru axle equipped bike with your wheel-on trainer, such as a 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other trainers.

    An additional benefit you will experience, once you switch to our threaded trainer axle, when riding outside with this axle your disc brake will no longer rub. This is due to the more consistent and greater clamping force of a threaded thru axle vs the RAT system. Consider our Lightning Bolt-on Front axle to rid your bike of the flex from the R.A.T.

    This axle is specific to bikes with FOCUS R.A.T. thru axles and 12×142 or Boost hub spacing. Includes a replacement R.A.T. nut with the Trainer Axle.
