    Hey, I’m a beginner commuter cyclist and bought a triban 500 SE after Christmas and have been riding about 20 miles a day since then, the biggest chainring (I think it’s Shimano Claris 50T) has become worn since I mostly ride on that one and am looking to replace it.

    I’ve looked around but can only find the full crankset for ~£50 but was expecting to pay maybe £10-£20 for just the chainring since the whole bike only cost ~£300 and can’t seem to find anywhere selling the individual chainring.

    Anyway, here’s the question, does anyone know where I can buy a replacement for the chainring or if I can just buy a similar chainring and use that, I’m new to all this so I have no idea what I’m doing.

    TLDR; need new chainring to replace Shimano Claris 50T but can’t find it online and don’t know what will replace it.

    I have a Cannondale with a (supposed to be rubbish) FSA Vero triple chainset, have ridden it really hard for 4,800 miles and the chainset is still fine. Its probably just the paint worn off.

    Before you go out and buy a new chainring I’d suggest taking it off and flipping it over. You’d lose any special shifting pins or ramps but you effectively get fresh teeth. If it doesn’t work out you haven’t lost anything, just buy a new ring as planned.

    The link above to the
    The link above to the Stronglight will not work for your chain-set, as yours is a 50t it will have the compact bolt pattern which is 110 bcd rather than the 130 bcd above. Also the Claris is an 8 speed chain-set, so a 10/11 speed ring will be somewhat too narrow, and allow a lot of chain movement, and spacing/offset will be wrong.

    You can get a replacement ring for around £16 here….

    Just look for a FC-2450 chainring online.

    Edit to say that the above number refers to the double chain-set, if you have a triple you need to look for an FC-2403 chain-ring.

    That sounds like a good idea
    That sounds like a good idea since I only really used one front gear anyway, any recommendations for the parts you used?

    And to everyone else, I made a big rookie mistake by being lazy in the winter and used a fairly rusty chain which ruined the ring, I recently swapped to a new chain but it slips on that single gear, any other gear works fine since I never used them much.

    I doubt your chain ring is
    I doubt your chain ring is dead but if you need a new one you can get different sizes off ebay for your bike. Theres no special shifting edges.. Its just stragiht chain ring.

    You might even want to do what i did for my bike and remove the triple, buy a Single speed crankset, choose one chain ring and get a square taper bottom bracket that keeps your chain line straight. Simple if you only use on Ring up front.

    Your chainring doesn’t need replacing after around 1800 unless you ride on a beach or something.

    If its just the anodization that has worn off, creating silver bits…the chainrings do not need replacement
    I really doubt that they do need replacing tbh.

    Even if it was Christmas 15 months ago, that would be incredibly fast chainring wear. Are you certain it needs replacing? 😕
