Sun Ringlé Rear wheel axle SRC/SRX

The Sun Ringlé SRC/SRX rear axle 148 mm Steel is designed to replace the axle of SRC or SRX hubs mounted on Sun Ringlé Atac and Duroc wheels. In this steel version, the Sun Ringlé SRC/SRC 148 mm axle is stronger but also heavier than the aluminum version. Please note: the name Duroc also refers to the rim only offered by Sun Ringlé. Some original equipment wheel assemblies may therefore have been made using a hub from another brand, such as Bontrager for Trek assemblies.
