I've just completed a couple of hundred miles on my first cross bike and I have to say it's a riot. I live in a place where it's pretty easy to ride some dirt trails and asphalt on the same ride and doing so has added a whole new dimension to the fun. Today I went out for a quick 12 around my village, 3/4 dirt/snow and 1/4 regular roads and it was a blast. My bike is equipped with Michelin Jets so the road riding is not too rough and yet there is enough grab to handle hard pack, sand and slop.
Honestly, I like it so much that I'm already thinking about my next one.
