Greetings all, new to forum, bit of help required.
I have recently upgraded my Felt z95 from Shimano Tiagra cassette and rear derailleur to 105. I'm an amateur but have tinkered successfully with a few set ups, but this has got me stumped.
I've set the limit stops and B tension screw according to various instructionals, and cable tension appears ok. Shifting is fairly sweet but when I'm in large chairing and work up to the 3rd and 2nd largest sprocket the angle the chain sits at in the derailleur cage causes the whole rear mech to jump and grind. The chain is angled outward as if the RD has gone too far in. If I shift into the largest sprocket the RD catches the spokes. Interestingly the small chairing shifts fine throughout the cassette.
The RD isn't bent, I can't see it being the limit stops or cable tension but it didn't happen on my Tiagra set up. I know I shouldn't run with large front large rear but thought I'd get away with 2nd and 3rd largest rear sprockets.
Any ideas?
