Yet another replacement chain on my Brompton :-(
I suppose I shouldn't grumble as I managed to get 6 months out of the previous chain, so about 1,000 miles. Total cost of replacement chain and sprockets = £25.00 Alternative cost of buying daily return tickets on DLR would have been £806.40!
Of course I had the additional cost of cleaning and lubrication products. For interest I clean the chain each week. My personal procedure is to clean the chain with Kaboom in a Barbieri cleaner, then I rinse the chain off with a hosepipe, wipe dry with an old cloth, turning the cranks I spray the chain with GT85 (to displace the water and add some PTFE), wipe dry again and then I oil the chain with Finish Line wet. I follow Sheldon Brown's advice on applying the oil. Depending upon the weather and conditions on my weekly commute, mid-week I occasionally wipe the chain with a cloth or wet-wipe and apply a bit more oil.
Stirred by a query by a London Brompton Club member, I decided to go for a KMC chain again (as opposed to SRAM or Wipperman). So X8.93 1/2 inch x 3/32 inch chain is now fitted and we'll see if I get much more than a 1,000 miles out of it in support of their guarantee...

What to do with the old, worn chain? Reduce/Re-use/Recycle - how about glueing it to the border of a plain picture frame?
