Shimano Alfine S7001-8 Internal Gear Hub

The Alfine S7001-8 houses all its shifting mechanisms inside the hub shell, protecting them from rain, grit, and road debris. This design significantly reduces maintenance requirements and allows for shifting while stopped, which is a major advantage in city traffic.

No, this specific model is designed exclusively for disc brakes using a Center Lock mounting system. You will need a compatible disc-brake wheelset to use this hub.

The hub features a Top Normal structure and a double roller clutch, which are specifically engineered to handle shifting under load. While it is smoother than many internal gear hubs, it is still best practice to ease off the pedals slightly during shifts for the longest component life.

The Alfine S7001-8 offers a 306% gear range. This provides a versatile spread that is well-suited for urban commuting and navigating varied city terrain without the complexity of a front derailleur.

This hub requires a rear spacing of 135mm and uses a 32-hole spoke count. You should verify your frame's rear dropout spacing before purchasing to ensure compatibility.

The Alfine S7001-8 weighs 1670g. While this is heavier than a standard derailleur and cassette setup, the trade-off is a much cleaner, more durable, and lower-maintenance drivetrain that is ideal for daily commuters.
