I need to buy a 50t chainring for my Mercier track bike.. it currently has the highest quality ebay truvativ crank-set and stock 48t chainring available...


I have been looking on ebizzle and other sites and i've come across plenty of matches but I'm afraid of buying the wrong size chainring.....

The chainring from my roadbike-FG conversion is not the same size as on the truvativ crank..

So let me get to the damn question: What size is the truvativ track chainring ?


Thanks !
