Centering Chainrings - Is it Worth it?
Not sure if this would be better place on the mechanics board, but I'd imagine a lot of people on here have experience with this.
I've nearly finished my first fixed conversion. I'm using a brand new 14t Surly Cog, 39t Campagnolo Xenon crankset (originally 52/39t) and KMC Z chain. The problem I'm having now is that having looked at Sheldon Brown's article on fixed conversions, he explains how to centre the chainring.
Now I've greased the washers between dropouts and axle nuts and really loosened the chainring bolts (I can wiggle the ring back and forth about 3/16") but no matter how hard I push the rear wheel up, when I tighten the right axle nut, the chain just won't bind at all. I've been able to get it so there's less than 1/4" of droop, but nothing more than that.
My question to you experts is, shall I just leave it like this? It is a new crankset of reasonable quality, maybe it just doesn't need centering?
