Technology:

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.

Cup and Cone Bearings
Angular contact ball bearings of the cup & cone type are superior to sealed cartridge bearings in terms of load carrying capacity, as they distribute lateral and vertical forces better, and thus run particularly smoothly and last a long time. They are also easier to adjust, maintain and replace.

Micro Spline
Micro Spline is an innovative tooth profile on MTB freehub bodies from Shimano. All Shimano 12-speed MTB cassettes with a 10-speed sprocket are equipped with Micro Spline freehub toothing. The significantly higher and finer toothing enables a stiffer connection between the cassette and the hub body. The resulting increased contact area ensures reliable power transmission, minimises wear and prevents deformation of the freehub and sprocket.
