Tires for gravel
My stomping grounds are luckily abundant with hard pack dirt, so I can get away with a 23mm Michilen Krylion carbon, for under 100 clams. The more loose or soft your surface, the wider tire with some tread would be better. In the past I've fit 27mm Conti Top Touring on my Colnago MasterXLight. Most carbon race bikes these days will accept 25's, that's good enough. Now get out there and ride the Vitamin G!!!!
