Cassette sprocket series from 7 to 13 speed — nickel-plated steel sprockets on a splined freehub body, with model-specific ratios from 11-25T road blocks up to 11-50T wide-range MTB blocks.
The CS Series covers cassette sprockets from 7 to 13 speed on one platform: nickel-plated steel sprockets on a standard splined freehub body, in model-specific ratios that run from tight 11-25T road blocks to wide-range 11-50T blocks for MTB and e-bike use.
Every model shares the same build principles: nickel-plated steel sprockets for corrosion resistance and long life, shift-gated tooth profiles for fast, quiet indexing, and a splined mount retained by a lockring (40 N·m torque).
Choose the speed count and ratio block that matches the drivetrain — 7S and 8S for entry and city bikes, 9S and 10S for road and trekking, and the 11S / 12S / 13S ranges for modern MTB and e-MTB groups, with model numbers CS732 through CS1350.

A stocked central spares warehouse guarantees critical-part dispatch within 24 hours to 40+ countries.
Our field engineers supervise on-site setup, alignment and first-run calibration, then hand over a signed commissioning report.
Customers who selected this product typically combine it with the following items.
Motorised lifting column with a quick-release clamp that sets a bicycle at the ideal working height in seconds — controlled from the handpiece or the foot pedal.
Dual-sided electric lifting column with two clamps on opposite faces — two mechanics work the same unit at once, each with their own clamp, hand controller and foot pedal.
Rotatable-type single-column electric lifting system with a quick-release clamp and hands-free foot pedal — raises the bike smoothly along a rigid column to the ideal working height.
