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.
