My 1994 Gary Fisher rigid, steel mtb passed away in the Fall of 2017 due to complications of a rusted out frame. The Gary Fisher was my Northeastern year-round, all-weather bike for commuting backforth to work. Instead of buying a new mtb, I decided to mount a pair of Schwalbe CX Pro tires on my SURLY Pacer road bike. Well, I got news for you sir. There isn't much that the SURLYCX Pro can't handle. I now ride onthru snow, ice, rock salt, gravel, dirt, and tarmac with full confidence. These tires are solid, relatively fast, and provide loads of traction considering they are only 30 mm. Best buy in a long time.
