E-Thru
E-Thru is a tool-free thru-axle system from Shimano that optimises the stiffness-to-weight ratio and ensures easy handling via its reliable internal cam mechanism. It is characterised by a high torsion resistance and thus also supports cornering at high speed. E-Thru thru-axle hubs and thru-axles are available in the corresponding over locknut dimensions for front and rear.
