I'm currently running 25s but would like to run 28s it I want to use the bike for touring as I could increase the pressures but keep the comfort. The question is would they fit in my frame? Any chance you could measure your new gatorskins for me? (height from rim edge and width). The measurements, 31 mm for 28 mm GP4000II tyres, given in malk's link seems really rather large and I'd like a second opinion.
Thanks.
