.....until exactly three weeks ago my ICE Adventure had approx. 2.5 x SRAM PC971 joined with three quicklinks.
Then, whilst climbing a steep hill, I changed down to the granny on the front, and heard a "zzzzping" before coming to a halt.
One of the quicklinks had come apart; I found one half on the road just behind me, but not the other. And to my dismay, the repair kit had neither a replacement quicklink, nor a chain splitter tool.
"Necessity is the mother of invention": a D-lock's steel cable (one end wrapped around the front derailleur post) acting as a tow rope makes the "walk of shame" home slightly less uncomfortable.
I had to clean the chain before refitting - I've also reduced the quicklink count to one. Oh, and there's a quicklink and a chain tool in the repair kit now........
