Slicks are great. I had some Specialized slicks on one of my mtb's. 1.25's At 80 psi they rolled fast and never a flat in 2 years, trail or street. I rode them inthe pouring rain once. 42 miles onthe trail and no hdroplane at all. When I sold the bike to a friend, I kept the tires. I payed abotu $20 each!
