right ive been setting up my bikes for yrs now but man this road/cross bike has me stumped. Ive moved the wheel right back into the drops (cross check) for a longer wheel base. Now i cant get the gears to run smoothly? I have however ordered a new shimano freehub body as this one is shot would that make a difference to the set up? Im stumped

B screw tensioner. May need winding out a bit now.

rickon… tried that doesnt seem to help though? the mech has moved abit further away from block now even with screw adjustments

Is the wheel defo in square?

yes wheel is square, there is some sideways play in the freehub so im hoping when my new one arrives it will settle down again.
