The Shimano Alfine SG-S7001-11 is a premium internal geared hub offering a wide 409% gear range across 11 speeds. Designed for disc brake use, it features an oil-lubricated system for superior durability and smoother rotation. The silent clutch and Top Normal structure provide a quiet, sporty shifting experience similar to high-end derailleurs.

This hub is compatible with Center Lock rotors and uses a 135mm bolt-on axle for secure frame fitment. At 1,665g, it provides a clean, low-maintenance alternative to traditional drivetrains. Note that this unit requires a separate small parts kit, including the shifter and cog, for complete installation.
