The 15mm Inspyre axle is specially designed to integrate a 15mm thru-axle configuration with a hub on the Inspyre Concorde V3 frame.
The axle is made from 7075-T6 aluminum and has been specifically developed for the Inspyre Concorde V3 2025, which features Swell V2.1 dropouts. Its length of 133mm has been carefully optimized to ensure the best fit on the frame dropouts, enhancing the rear triangle's stiffness while maintaining the necessary space for perfect hub compression in the frame, without the need for additional spacers.
The axle also ensures excellent bike performance, offering perfect support on the frame thanks to the wide cones at both ends. Using a 15mm thru-axle setup also simplifies the installation and removal of the rear wheel.
