Just installed a pair of semi-slicks Michelin Country Road 1.75 tires on my RockHopper. The thought was that since I'm doing mostly paved roads (90% paved and occasional weekend on trails) I'd be better of a pair of semi-slicks than on a pair of knobies. Yes, I know a road bike is
the real solution but living in NYC I don't really have space for an extra bike.
I wasn't sure what to expect from semi-slicks but hoped for some speed pick up. Well, I think I get some speed pick up in higher gear - I think it's a little easier at speeds ~20mph but at slower speeds I can't really see a difference between my old Specialized knobies and new semi-slicks. Is this normal? Or maybe I should just switch to slicks?
