Axes
The core of this hub´s superior front-end stiffness is its compatibility with modern thru-axle standards. The SHIMANO M618B is engineered specifically for the 15mm E-Thru axle system with a 100mm Over Locknut Dimension (O.L.D.). This tool-free system not only simplifies wheel removal and installation but also creates a significantly stronger and more secure interface than traditional quick-release skewers. This results in less wheel flex under load, more precise handling, and the confidence to push your limits on the trail.
