Wide Flange


SHIMANO's extra-wide hub flange increases the triangulation base between the two hub flanges and the rim thus maximizing lateral rigidity. With a reduced spoke angle on the cassette side this design provides increased lateral rigidity and more uniform spoke tension on the drive and non-drive sides. Wheels equipped with this flange deliver class-leading torsional and lateral rigidity and offer boosted power-transfer efficiency.
