adjusting RD - fine by hand, can't rear largest cog when assembled
Had to replace a hood on the shift handle, so I disconnecting a beutifully adjusted Shimano Dura-Ace RD. Upon reassembly, I can't get it to shift into the largest cog. If I pull the cable at the downtube by hand the RD moves to the right spot under the largest cog. When I try to tighten the cable the RD always relaxes down one gear. I tried the barrel adjuster but that didn't do it. Any advice?
