Is the WHEELTOP EDS TX/TT/TXF Rear Derailleur Pulley Cage compatible with my bike?

The WHEELTOP EDS is compatible with 11-speed and 12-speed cassettes, and works with most modern frame types and chain brands. Check the product page on Aoeagle for exact compatibility with your specific shifter system (Shimano, SRAM, or Campagnolo), as derailleur compatibility depends on your current drivetrain setup.
