The 11-30T configuration provides a balanced range for riders who want closely spaced gears for general cycling and varied terrain.
11-32T
11-13-15-18-21-24-28-32
The 11-32T option provides an additional low gear for riders who regularly encounter moderate climbs while still retaining an 11T high gear.
11-34T
11-13-15-17-20-23-26-34
The 11-34T configuration offers the widest low-gear option among the listed combinations, making it suitable for riders looking for easier gearing on steeper climbs and demanding terrain.
Designed for Mountain and Everyday Cycling
The Shimano Altus 8 Speed Cassette is intended for mountain applications and can be an excellent choice for compatible MTB drivetrain setups. Its available gear ranges make it suitable for a variety of riding conditions, including city cycling, recreational rides, trail riding and routes with elevation changes.
For a smooth drivetrain experience, the cassette should be used with compatible components and installed correctly. Riders should check their existing cassette, rear derailleur capacity, chain compatibility and drivetrain configuration before selecting the required tooth combination.
