Rode in today on the new conti twister cross tires and they work great so far. There was a little ice in certain places so I was taking it a little slow and when I took off from a stop I could feel the back tire slip a little. Yesterday I took them for a test ride through some muddy trails near my house which was a blast, I could ride one trail and then be back on the street for a bit and then jump into another, fixed off road is a good time and a lot of work too.
