Precision-machined replacement thru-axle for bikes that easily adapts any 12mm thru-axle system to firmly lock into bike trainer cone cups. Specifically made to work on Kinetic trainers, Traxle works with most other trainer brands. Perfect for bike shop fitting stations and at home-use. Unlike stock thru-axles, the Traxle has tapered heads that stand out just far enough from the bike frame to fit into the trainer's cone cups. Can be used for outdoor use.
This is a great fit for 142x12 axles found on Cannondale Slate, 2018 Synapse, 2017 SuperX, Scalpel 29, Scalpel Si, and others using the Syntace X12 axle. Not compatible with Maxxle systems as that has a different thread pitch.
