Up til now I've been riding an MTB as a sort of "urban dreadnought", so they're 26x2.1 with a marked range of 35 - 65psi. I've been keeping them around 50 and that's seemed to work rather well.
But I'm switching over to an older mixte tourer, with narrow hi-pressure 27 inchers, so that feels more scary and prompted my question. Since I'll still ride in the same manky urban roads, I'm wondering whether I can switch down to 650s or at least 700s and fatten up the tires. But I don't know yet whether that will bugger up the pedal clearance...I might be stuck with the 27s.
