All these zip ties has now given me the idea that I should really bring some with me when I ride. Currently I only bring multi-tool, pump and inner tube.
I just found this old pic. The rack mount sheared off the frame; this hose clip and gaffer tape bodge lasted the next 600+km to the end of the trip. I split a tyre sidewall the same day; gaffer tape to the rescue again, making a tyre boot that lasted two days until I scored a $2 Chinese bike tyre in a street market.
Off again in two weeks - for a three month trip on a bike with an utterly knackered drivetrain. I'd better start looking for zip-ties down the local market....
