I'm running 700 x 25 Specialized Armadillos on my bike. There is practically no clearance between the band on adapter for the front derailleur and the tyre. It seems to be fine but when It rains it picks up muck from the road and seems to collect there and can make an annoying noise. Would going down to 700 x 23 just reduce the width or would it give me extra clearance at the band on adapter as well? Thanks.
