I have an FSA Pro Road 44t chainring (5 arm, 130BCD) which has done no more than 100miles or so. A couple of scuffs etc as you would expect, but no damaged teeth and not worn.
Would be ideal for a cyclocross bike or hybrid / commuter. It will work with 9/10 speed chains, but no reason for it not to be used with a singlespeed build too (I had it set up with a 1x10 bike, but have decided to go with a different ratio).
It is is the same as the ring CRC sell for £32 here - http://www.chainreactioncycles.com/Models.aspx?ModelID=35784
Looking for £22 inc postage. Email in profile.
