Triban 500 Shimano Sora question

I have a B'Twin Triban 500 with triple Sora crankset (50/39/30).

Does anyone happen to know which type of 50T ring it uses as I need to replace it? I think it's an FC-3503 but I'm not 100% sure.

If anyone knows, or knows where I should look if it's stamped on anywhere, then please let me know... Ta :smile:

Is it a Shimano Crankset or a pro-ounce one?
There is usually a marking, sometimes on the inside of the crank arm which will say something like 110BCD or 130BCD. As long as you get a matching chainring with that same BCD all should be well :smile:

Thanks all, I'll know where to look now.

@bikingdad90 - it's a Shimano Sora, not the Pro Ounce (or "Dunce", as it looked on the crank arm ^_^)... Mine was a later one after they swapped over (though still with the Microshift derailleur, which is actually pretty decent).

Rather annoyingly I don't see BCD-anything. However the measurements between the centres of the bolts indicate a 130BCD.
