• Having fiddled a bit more and ridden up and down a bit, I've come to the conclusion the chain may be part of the issue, as the stickinging/slipping always seems to come in the same place/rhythm-so I wonder if a stiff part is the issue or a chain pin out of line that catches on the cage.. It's a Renolds 1/8th period chain, which I've always found to be quite a beefy chain, so I may try a modern 1/8th to see if that runs better.....

  • The flat coiled spring was good at grabbing mud and creating a grinding compound. I wonder if there is any wear inside the windings of the spring causing friction, or just enough to make it hessitate to accomodate the next cog - did that make any sense !?
