⚡ At a Glance
- • Fit Compatibility: Adapters for a range of cassette and hub combinations, including adapting 7, 8 or 9-speed cassettes to 10 or 11-speed hubs and enabling 10-speed cassettes on 11-speed hubs
- • Best for: Home mechanics and riders updating drivetrains who need precise spacer options
- • Not ideal for: Bikes with hub spacings or proprietary parts that fall outside the listed compatibility notes
Eight spacers in seven thicknesses allow flexible cassette positioning. Precision-machined grooves reduce rotational vibration and help protect adjacent components.
Precise chainline adjustment – Thanks to seven distinct thicknesses
Set contains eight spacers with thicknesses of 1.0, 1.5, 1.85, 2.0 (two pieces), 2.18, 2.35 and 2.5 mm, each machined with grooves to tight tolerances.
Fine tuning of cassette position helps reduce rotational vibration and improves shifting consistency, making drivetrain setup more reliable.
Lightweight durability – With aluminium alloy construction
Top-tier aluminium alloy gives a low mass, strong spacer that resists deformation, while precision machining preserves concentricity under load.
Durable adjustment parts that will not noticeably increase wheel mass and help prolong the life of neighbouring components.
Fast maintenance and fitting – With simple, tool-friendly design
Washers are designed for straightforward removal and installation without complex procedures, allowing single-person adjustments in a workshop or roadside situation.
Quick to swap during cassette changes or when troubleshooting gear rub, saving time and keeping the bike on the road.
