Hi, new here. Has anyone tried the Serfas Drifter City 26x1.5 tires? I installed a pair on a 1997 Trek 820 Mountaintrack along with a Bontrager rear rack, to turn a vintage MTB (no suspension) into a hybrid commuter of sorts. I only put about 5 miles on tarmac, and they seem to roll much better than MTB tires, but haven't tried anything else. What I'm wondering is how they will do on country gravel roads and crushed limestone trails. This bike will be ridden 85% tarmac, 10% gravel and 5% crushed lime stone. I hope I made a good choice. Anyone tried a similar set up?
