Compatible with SHIMANO 8/9/10/11-speed mountain bikes, ensuring compatibility with various speed systems, whether it is upgrading or daily maintenance, it can provide precise matching and stability.
The size is 40.5x34.7mm, which fits tightly with bicycle parts, reduces shaking and abnormal noise, and improves riding comfort and safety.
Small accessories are very useful. They are needed to adjust the height of the flywheel when modifying the flywheel!
Note: When installing the 8/9/10-speed cassette flywheel on the standard road bike 11-speed cassette freehub, a 1.8mm standard thickness gasket is required for adjustment. If the mountain bike hub normally supports 8/9/10/11-speed mountain bike flywheels, but when installing the 7-speed cassette flywheel, 2 2mm gaskets are required for normal use.
The cassette design makes the installation process simple and quick. Without complicated tools, the gasket can be easily replaced or installed, saving time and energy.
