Hi Jeff,
Thanks, could you guide me what to do with another strange problem i have, my groupset is Dura Ace EX with 6-speed Uniglide cassette.
I installed a new chain SRAM PC890 and i have huge problems figuring out why the chain won't mesh with the smallest cog when i am running it on the largest chainring, i don't know how the old chain behaved as i binned it which i regret now.
I tried everything, i have lubed the cable to the DR and checked it moves freely which it does, i have adjusted the triming screw on DR, i can make the chain mesh with smallest cog if i move the adjustment screw very far out, but then it will jump out of the sprocket under load as it's already too far out.
After reading forums they say this chain should work great with Uniglide 6-speed.
I don't have any problems when chain is on smallest chainring and moving to smallest cog at the back, only when on largest chainring.
The derailleur hanger seems straight as well.
If you can give me any advice i would be happy, this is driving me nuts right now....
