The Twenty21 11-Speed Cassette (11-46T) is an excellent choice for gravel and mountain bike riders looking to upgrade or replace their drivetrain components without a high price tag. It provides a wide 418% gear range that helps riders conquer steep climbs while maintaining speed on flat sections, though its 555g weight may be a drawback for weight-conscious racers.

Yes, as long as your rear wheel uses a Shimano HG style freehub body, this cassette will work with most 11-speed indexing systems.
The Twenty21 11-46T cassette weighs approximately 555g.
No, it is compatible with standard 11-speed bicycle chains.
Most road derailleurs do not have the capacity for a 46T cog; ensure your rear derailleur is rated for a 'wide-range' or 'mountain' setup.
The 46T sprocket is constructed from 7075 alloy to reduce weight.
Check your derailleur's B-tension screw and adjust it to move the upper pulley wheel further from the 46T cog.
Ensure the lockring is tightened to the recommended torque and verify that all spacers are properly seated.
This cassette is compatible exclusively with Shimano HG style freehub bodies. When installing, ensure the freehub splines are clean and apply a thin layer of grease to prevent seizing. Use a standard cassette lockring tool to tighten to the manufacturer's specified torque. Because this is an 11-speed unit, verify that your rear derailleur has the capacity to handle a 46T cog, as some older short-cage derailleurs may require a longer hanger or a derailleur hanger extender to clear the large 46T sprocket. Clean with a degreaser after muddy rides to maintain smooth shifting performance.
