I am getting back into cycling and am moving towards light touring/credit card touring. I am shorter and some of the bikes I am looking at, Soma Saga for example, only come with 26" wheels in my size. Though I have seen guys saying 700c is better for touring. Is there a reason not to go with a 26" bike for touring? I know the wheel is smaller, but isn't that made up for in gearing?

Thanks for the help! Chris
