2 new gear cables, 1 new tube, and a chain link. Those are the bike parts we have gone through so far.
Each of us snapped a gear cable. We haven't had any new flats but I had a flat just before we left Vancouver. I tried patching it twice but it continued to leak slowly so we finally put in a new tube.
My chain broke just as we were rolling into Honey Bear RV park to stay for the evening. I tried repairing the broken link but it was bent badly. Luckily Helen had also stopped at the same campground and she had a spare quick link that she let me use.
My 12 year old camp stove was also having issues. But we found a store selling a repair kit and after replacing a few parts it seems to back to normal.
The good news is that we have been able to make all these repairs ourselves.
