how about we go back a bit first.
Do you presently own a touring bike, if so, which one?
It it is a stock model, generally the stock wheels will be fine for touring with stuff on the bike, but lets get this question out in the open first.
Also, if you are of average weight and plan to carry an more or less average 30, 40lbs of stuff on your bike, then a reasonably priced set of wheels will work fine.
Oh, 700 or 26in wheels, or something else?
Enquiring minds want to know (and it will make all the diff in the answers that will be helpful)
I have a Trek CrossRip 2 with disc brakes. Its a gravel bike that supposed to support light touring and it comes stock with "Bontrager Tubeless Ready Disc 700c, 32h" which I've been told are skinny road rims that wont support a tour. I am planning a week long tour around up-state new york this summer so it wont be a long tour but I really dont want to have any issues with my rims. I am about 230lbs and will be carrying like 30lbs probably so I want something strong.
