When is a tire fit and chainstay clearance too tight?
I'm considering a 700x38 tire that measures 37.5mm wide. The frame will not allow a 700x40 that I use on another bike (it measures 40.5mm). I tried this size and the shoulder knobs gently scrub the chainstays.
I've calculated that each side of the 700x38 tire will have about 2.5 to 3mm clearance. The widest part of the tire of the 38 is a slightly smaller radius than a larger diameter tire and the chainstays spread out as they move back.
Well, any opinions? Is 2.5 to 3mm clearance on each side enough?
