No word on a spare cable or two. Seems I’m pretty good at breaking a rear derailleur ca ble. Last summer I actually broke front. Here’s a tip on what tools to carry.–Corrie
As long as you ride a well-maintained bicycle, serious breakdowns should be pretty rare. Out on the road or trail you’ll mostly be repairing the occasional flat tire because it’s hard to avoid every piece of glass, and those rocks and potholes out on the trails. But other than that, it’s amazing how long a maintained bicycle will run trouble free.
