These axle end supports are used on several Mavic road hubs including but not limited to Ksyrium SL, SLR, SLS, R-SYS (2013), Ksyrium Elite S (2013). Sold as a pair. Mavic Part #: 351 173 01
Rogue Mechanic was the only place I could find the Mavic road axle support for a 2007 Mavic Elite wheels & hubs. Not even Mavic themselves had these available. Fit perfectly without any issues - Thanks
