The 53 ring usually too much for my riding ability (the 39 is okay). Is it possible to change the 53 to a 50? Is such a chainring available using the 130mm bolt. Can I use any brand of chainring or do I need a specific FSA one? Final question, where would I find a 50?
BTW, I used to ride a compact 50/34 but I found the 16 teeth difference too much, it also lead to the chain being dropped.
