FC-4703
This genuine Shimano chainring is the 39T middle ring for the FC-4703 Tiagra road crankset. It is a direct replacement for a worn or damaged middle ring, helping you keep your existing triple drivetrain in service without replacing the complete crankset.
The ring is made for Shimano’s 3x10-speed, 50-39-30T crankset configuration and is intended only for the FC-4703 system. Its teeth are developed to work with Shimano HG-X 10-speed chains, supporting efficient contact and power transfer through the drivetrain.
Check your crankset model and gearing before ordering: this ring is not a general-purpose replacement for every triple crankset. The 110 mm, 4-arm format, black finish and supplied nut and holder make it a practical service part for a matching FC-4703 setup.
Ideal for anyone refreshing a worn middle chainring on a Shimano Tiagra FC-4703 50-39-30T, 3x10-speed road crankset.
Genuine Shimano replacement
A replacement middle chainring made for the FC-4703 crankset, rather than a generic triple-ring substitute.
39T middle ring
Restores the middle position in the original 50-39-30T gearing combination.
FC-4703 specific fit
Designed for Shimano Tiagra FC-4703 cranksets with the matching 3x10-speed triple configuration.
HG-X 10-speed compatibility
The tooth profile is intended to work with Shimano HG-X 10-speed chains for efficient chain contact.
110 mm, 4-arm pattern
The specified bolt pattern helps you confirm fit before ordering.
Replacement for worn teeth
A sensible service option when the middle ring is worn or damaged but the rest of the crankset remains serviceable.
Nut and holder supplied
Includes the nut and holder listed for this replacement chainring.
