Putting together my daughter's old Pinaello Dogma race bike for her and I'm having problems.
When it was her race bike it was kitted out with Campag EPS and everything worked perfectly. Lovely. Her Team bike made the Dogma redundant and it eventually got stripped for parts and shoved under the bed to gather dust for a few years. For nostalgias sake she wanted to get it built back up and ridden, so she had it repainted, sourced a used Ultegra Di2 groupset from a mate. Should be easy .......
Disclaimer: I know next to nothing about Shimano parts, all my bikes have been Campag (sometimes SRAM)
All done, all works but cannot get final adjustment of rear mech right. Even with limit screws backed right off, I cannot get the chain to climb onto the largest cassette cog. It also tries to drop off the smallest cog, and I can adjust this out to prevent it, but it still won't climb into bottom gear. It's as if the whole rear mech is sitting a few millimetres too far outwards. Weird.
The amount of shifting travel is dictated by the electric moor, but there is a fair amount of 'backlash' in the mechanism. Is there any way of adjusting this out which would move the jockey cage inwards.
Last resort would be to machine a few millimetres off the mech hanger, but it's a bit of a pain as I no longer have access to a milling machine.
Any suggestions or advice?
