The Wheeltop RDDP780-GS oversized pulley cage is an upgrade for EDS TX rear derailleurs. It combines a 93 mm carbon-fibre cage with 12T and 18T oversized pulley wheels, ceramic bearings and a reflective finish.
The larger pulley wheels reduce the amount of articulation required as the chain passes through the derailleur, while the ceramic bearings help minimise pulley resistance. The system retains a 36T derailleur capacity and supports cassettes with a maximum sprocket between 30T and 36T.
