I'm trying to get a 7 speed Shimano 300EX rear derailleur to index using Exage sport shifters.
It seems I can either get the low range of the cassette shifting smoothly or the high range,but not across the whole range.
When I adjust the tension on the cable so that the chain will climb up onto the largest cog on the cassette it will then not move back down below the 4th cog!!
The shifter cable is new and all the components,derailleur,shifter and cassette are in excellent condition.
I have no experience of doing these,by the way and may be missing a trick or two.
Any help will be most gratefully received!
