Why Is the Shimano Altus CS-HG31 a Practical 8-Speed Cassette for Budget MTB Builds?

The Shimano Altus CS-HG31-8 is an 8-speed MTB cassette built on Shimano's HYPERGLIDE platform, delivering reliable indexed shifting with the specially positioned shift ramps and tooth profiles that define Shimano's cassette shifting performance. The Mega Range 11-34T gear spread gives riders a genuinely usable low gear for steep climbs without requiring any mechanical compromise elsewhere in the drivetrain, making it an effective choice for recreational MTB and hybrid builds on tighter budgets.

Compatible with all Shimano 8-speed MTB drivetrains. Requires a standard Shimano 8-speed freehub body and an 8-speed chain.
