After cruising around the county on my not so squishy but highly flotational and nicely performing Pasela 32's for a month, I decided to put some Ruffy Tuffies (27mm) on my steel "fast" bike. Man, let me at those chip/seal, potholed roads! No more bounce and rattle.
BUT, I hadn't figured on the short reach limitations of my old Superbe Pro brakes. There is not enough tire clearance with the Ruffies to avoid rubbing against the bottom of the brake bridge and skim the bottom of the calipers.
I don't agree with Grant on everything, but the longer reach brakes and frames to match them make sense..... some of the best roads around here that carry you to the best places are often the "worst" roads in terms of maintenance and condition.
The fast bike frame looks cool with tight, minimum clearances everywhere. But, in this case, "cool" can be a pain.
