What to Compare Before Buying
- Driver interface: Confirm that the rear wheel has an XDR driver body.
- Drivetrain configuration: Check that the 12-speed specification and 10-36T range are appropriate for the existing setup.
- Replacement identity: Compare the Force XG-1270 E1 name and part number 00.2418.159.003 with the cassette being replaced.
Before You Decide
Check the wheel’s driver body and the bike’s drivetrain requirements, then confirm the model and part number. The XDR specification alone does not establish compatibility with every bike or drivetrain.
