Do you ever worry about traction or riding in the rain, sharp or fast turns? On my street mt. bike I have Michelin CiTY semi-slicks (has grooves). The grooves gives me some confidence, yet I worry about wiping out on sharp turns, especially if going downhill where there is a sweeping turn at the bottom. How do you slick guys do it? Reason I'm asking is that some guy is selling two NEW Forte 26 x 1.5 pure slicks for $10. Too good of a deal to pass.
