not planning to put any major loads on this...today i made my first trip to Trader Joe's on the bike...of course, limited to how much i can get (it all fit fine in the back pack). pumped these bontrager comforts up to 80psi...it was an easy, hilly go.

glad to know that 1.5 should hold a load fine.

would (michelin) 1.75 be much of a sacrifice of control and zippiness when i'm not doing chores on the bike and want to hit the road or trail?
