Axle

The Unisky -3 In 1 Thru Axle is designed for indoor bike trainers, serving as a replacement for the original rear thru-axle to facilitate secure mounting of the bicycle onto the trainer. It includes three threaded end pieces with pitches of P1.0, P1.5, and P1.75. When replacing the original thru-axle with this product, first identify the thread specification of the original thru-axle, then select and assemble the end piece with the corresponding thread pitch. The product also comes with four adjustment spacers. These should be installed according to the shape and spacing of the bicycle frame's rear dropout to protect the frame and ensure reliable rear wheel locking. Important reminder: After using this product on the trainer, promptly reinstall the bicycle's original thru-axle. Do not use this product for outdoor road riding to avoid safety risks due to improper use.
