Hi all,
I am trying to replace my Shimano Tiagra FC-4503 50T Chainring 130mm (Shimano part no Y1H798030) but am really struggling to source one. I have looked at various alternatives but as my bike is a 9 speed, am concerned of a mismatch. I have narrowed my search to the following items but would appreciate any advice/recommendations,
Shimano Tiagra FC4603 Triple Chainring | Chain Reaction Cycles
Shimano Sora FC3403 Triple Chainring | Chain Reaction Cycles
Thanks!
Aaron.
