Trainer Axle: Length 151 or 157 mm Surly GnotBoost (TRA218)

Our Surly Trainer Axle is designed to adapt your Surly MDS/Gnot Boost bike with your wheel-on trainer, such as a 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo and many other trainers. 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. Train, warm up and be race ready and fit for the season.

This axle is for Surly bikes with the MDS/Gnot Boost system.

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.
