I gave the Carlton some time today. I removed the chain, derailleurs, shifters and crankset in preparation for the VX upgrade and original cottered crankset refit. Next up will be to remove the bottom bracket, clean, then refit the cottered spindle. It’s all quite grimy around the bottom bracket shell, so a good clean is required there too. I’m dropping to a 49 tooth outer ring from a 52 tooth, so I’m guessing I might need a new chain when the time comes. Hopefully more progress will be made over the Easter weekend.
Edit… I meant I should be able to use the existing chain and shorten it if needed.
