Trying to get the rear mech set up properly on the Viner, not set up downtube shifters for a while.
Can't get the chain to stay in the largest four sprockets on a six speed block, cable tension seems to slacken off and the chain drops into the two smallest sprockets.
Symptom of too much cable tension ? Cable is fairly slack in the smallest sprocket though. Anything else that could be causing it ?
I had a similar problem with some campag friction shifters.. I boshed an additional plastic washer in there and tightened it up and seemed to solve it. Also maybe there's too much / wrong sort of grease in there?
