Shimano Tiagra RD-4700 10-Speed Rear Derailleur Pulley Set
What Does the Shimano Tiagra RD-4700 Pulley Set Do and When Should It Be Replaced?
The RD-4700 pulley set contains the guide pulley and tension pulley that route the chain through the rear derailleur cage on Shimano's Tiagra RD-4700 10-speed rear derailleur. These two pulleys are the highest-wear rotating components in a rear derailleur: the guide pulley contacts the chain on every link with lateral movement during shifts, and the tension pulley runs under constant spring load throughout the drivetrain's operation. Over time the pulley teeth wear into a rounded or asymmetric profile that allows chain slop, increasing shift noise and reducing the precision of gear engagement. The pulleys use a low-friction bushing bearing design specific to the RD-4700 derailleur cage geometry, sized to fit the existing cage pivot bolts without modification. Replacing worn pulleys restores derailleur chain tracking and eliminates the chain rattle and sluggish shifting that develops as pulley teeth round off.
This is the OEM replacement set for the RD-4700 and includes both the guide and tension pulleys with the correct tooth count and spacing for this derailleur. Pulley replacement is one of the lower-cost drivetrain services available and is often done at the same time as a chain and cassette swap. The RD-4700 derailleur cage is specific to this model and does not accept pulleys from Dura-Ace or XTR-level derailleur cages. For Tiagra RD-4700 riders experiencing increased drivetrain noise or less precise rear shifting on an otherwise well-adjusted derailleur, new pulleys are a quick and effective fix.
