You mentioned getting a RD-M735 and the long cage version should work well in friction mode. The RD-M735 is one of the few Shimano RDs that have a tension adjustment on the parallelogram. Control is via the small screw behind the cable attachment bolt. Could be useful when running friction mode to balance how tight the shifter attachment screw needs to be to keep it in gear. Down tube shifters usually don't have as much cable drag/stretch and won't require high tension from the RD.
Good luck.
thanks for the info.
i did indeed pick up a rd-m735. probably get it by the end of the week or so
it was mentioned in an earlier post that derailleur technology had advanced in the geometry department in the late 80s. would this apply to front ones too?
i have an issue with my front derailleur; i put in a sealed bottom bracket and it pushed my chainline out just a tiny bit, but it's enough to make the inside ring just barely shiftable.
also, the limit adjuster screws got corroded into the housing, and i stripped the heads getting them free. i can turn them with great effort, but days are numbered.
so, i'm going to have to replace it anyway, should i go for a later derailleur?
any opinions?
thanks,
