yeah I was thinking that too, so thanks for the input..I don't use the 48 often, I usually use it on downhills if I want to go faster or keep cadence. But honestly I get going to damn fast I back off usually. So I mainly use the 32 around town and off road. And yes you are correct I do a mixed bag of riding. Just stuck on matching the 105, but I think it's probably not the best idea given the realities.
