Shimano Cassette Spacer – for 10-Speed Cassette on 11–12-Speed Freehub
Description:
This Shimano-compatible cassette spacer is used to mount a 10-speed cassette onto a Shimano/SRAM HG 11–12-speed freehub body. Modern 11–12-speed freehubs are wider than 10-speed cassettes, so this spacer is essential for correct installation and proper drivetrain function.
Installed between the freehub and the cassette, the spacer compensates for the width difference, preventing lateral play and ensuring correct chainline, accurate shifting, and smooth, quiet operation.
