KMC React HG 11sp Cassette

Each REACT Cassette utilizes carefully crafted shifting ramps to control chain flow. The unique lifting-ramp design carries the chain smoothly upward on the cog while the distinctive lowering-ramps adeptly align the chain quickly. Both result in improved shifting performance and overall component interaction efficiency and stability
