Traxel Trainer Thru-Axle

While more and more bikes are coming with thru-axles, it doesn't mean those bikes won't fit in the trainer for some much-needed sessions this winter. With the Traxel Trainer Thru-Axle from Kinetic, you can put your road disc, gravel, 'cross, or mountain bike on the trainer using this precision-machined replacement thru-axle. It uses tapered heads that sit just far enough away from the bike's dropouts to fit the trainer's cone cups. Traxles come in 12mm diameters and firmly lock your bike into Kinetic trainers and may fit others too.

The Traxles are available in 4 lengths depending on the thread pitch and it is recommended to use this guide to determine the right axle for your bike. Kinetic even gives its blessings for everyday use so you can leave it on the bike and ride outside when the weather's nice too.
