I have a Trek Verve + 3 that I ride pretty much daily, 30 to 40 km. In the 6 weeks I have owned it, I am coming up close to 2000 total kilometers. I ride for recreation and exercise, on streets, paved tracks, gravel trails and some single track including in a nearby provincial park. I am often away from roads by a kilometre or two. I carry a tire repair kit and spare tube, tape, zip ties... anything else I should have? How likely am I to break a chain with this type of riding? Also, the 700x50 Bontrager hard case tires on the bike are great but very smooth... any recommendations for a bit more trail-friendly tire and for fall/winter? Thanks in advance.
