just slapped on a fancy new 45nrth xerces tire on the rear wheel of my trusty kona dew fs winter bike, to replace my now-janky schwalbe snow stud. the new one is thinner – 700x30c rather than the 38c I had been using in the winter. and 140 aluminum carbide studs. should be fun on the icy morning rides, while still being fun on the melty afternoon rides home
