Easier hill climbs - thanks to the 11-34 tooth range
A larger 34-tooth sprocket reduces the gear ratio for low gears, lowering the force required at the pedals. The 11-tooth high end keeps top gears usable on flatter sections.
Steeper ascents become more manageable, useful for loaded touring, hilly commutes, or carrying panniers.
Predictable cadence changes - with 9-speed spacing
Nine cogs are spaced to provide steady steps between gears, making cadence adjustments smoother. Consistent sprocket spacing helps maintain chain engagement across shifts.
Gives reliable, repeatable shifting feel for training rides and daily commutes without unexpected jumps between gears.
Straightforward upgrade - with standard 9-speed design
The Alivio CS-HG400 follows common 9-speed cassette dimensions and spacing, permitting direct replacement on compatible freehubs. Installation typically needs only basic tools and a cassette lockring tool.
