Chainring compatibility

    I've an FSA triple chain set (53/42/30) which was originally part of a 9 speed campag xenon group that has had shifters, chain, and casette upgraded to 10 speed veloce. It works fine, outside of shifting up from 42 to 53, which can be finicky. I suspect this is down to a narrower chain, and worn ramps on the outer chainring.

    New chainrings were on my list to replace next, but I'm wondering are there any compatibility issues. Measuring bolt centre to crank centre suggests 130BCD and I'm wondering will any 5 bolt 130 BCD 53T (or 52T) ramped outer chain ring work? Chain is a standard veloce chain. Looiking at this as an option.

    Picked this one up on ebay, hopefully does the trick. It looks as though the veloce chain is nearly a full millimeter thinner than the campag compatible KMC and BBB 10 speed chains, which at a guess will reduce potential for derailleur rub, but also increase reliance on ramps when shifting up in the front.

    Was looking to possibly replace the whole crankset, but all the campag ones seem pretty expensive, with even chain rings way more than shimano.

    Arrived yesterday, fitted last night, and all now seems well. Ramps worn smooth on the old one, only really noticeable when I took it off.
