I'm interested in replacing my double chain ring set up with a single (fewer hassles with FD, easier on my brain not to have to think about shifting in front, and heck, the pros are doing this).
Here's my question: how exactly do you do this? Is there special single chain ring crankset for CX, or do you use a track/fixie crankset (I'm thinking problems with compatibility of bigger track chainring and smaller 9 or 10 speed cogset). Or do you just remove the smaller ring, FD and shifter cable, and let it go at that?
From a previous post you may know that I changed my 36/46 set up to a 36/42. Now I'm thinking just 42, period.... Advice?
You can use a standard road crank. You have two options from there, largely determined by your bike. One is two run a guard/ring/guard or keeper/ring/guard. The double guard is better but many chainstays won't accommodate it. If you get a keeper get either an N-Gear Jump Stop or a K-Edge 'cross specific keeper. I have both keepers and like them equally.
Generally people also get a brake lever only hood (or remove the internals from a SRAM shifter) to get some weight savings too.
In that case, follow Chris's advice.
You will need a 'keeper' for the chain! You can do it a few ways, but the most elegant is the Paul keeper
not cheap, but worth it.
OR just go 1x1 :-)
