Riders with a Shimano Sora FC-3503 triple crankset whose outer ring is worn, bent or damaged.
The Shimano Sora FC-3503 50T is the genuine outer chainring for the 9-speed Sora triple crankset in its 50-39-30T combination. It bolts to the 130 mm, five arm spider, with shift ramps and pins that are timed to work with the matching 39T middle ring.
Using the correct Shimano ring matters on a triple. The shift ramps are designed to lift the chain up from the middle ring at the right point, so a genuine part keeps front shifting as crisp as it was when the bike was new.
It is finished in black to match the original crankset.

Chainring
Great for
Maybe not for
Made for the Shimano Sora FC-3503 triple in 50-39-30T. Check the markings on your current rings before ordering.
Change the chain too
A worn ring usually means a worn chain. Check chain wear first, as a stretched chain on a fresh ring will skip and wear it out fast.
Line it up
Fit the ring with the crank arm pin or marking lined up to the crank arm so the shift ramps sit where Shimano intended. Tighten chainring bolts evenly in a star pattern.
