I want to trade up from my current 700 x 28c tyres on my not-great-but-it'll-have-to-do bike (see here, not recommended if you are eating!) to 32s, for comfort reasons - the ally frame transmits every bump, and I'm breaking in a Brooks! My riding is mainly tarmac but some towpath as well. The friendly guy in Johns Bikes Bath recommended a Bontrager, which I assume was the race lite hardcase. He said he put it on his winter bike and he wasn't any slower for it. Obviously the tyre needs to roll like a well greased bowling ball, be 100% immune to p*******s but also weigh nothing. And be dirt cheap. Seriously though, my priorities are rolls OK, no tread, doesn't weigh a ton and doesn't cost a fortune (think £20 per tyre). Any recommendations?
