I'm converting a Giant 2006 carbon road bike to flat bars. It has this setup:
Ultegra 6600 Triple, braze-on mount, bottom-pull, 52/39/30
105 5600 10-speed, 12-27
I have a set of SLX M670 10-speed shifters I'd like to use. The cable pull is (apparently) wrong on both ends, so I'm looking for replacement derailleurs.
What front derailleur can I use with these shifters that'll work with a braze-on mount? It's not clear to me which, if any, Dyna-sys derailleurs fit this frame. Or if any of them can handle the 52T ring.
The fallback is to give up and buy a set Shimano R770(?)/R780 or Microshift TS83-10. Microshift and R780 seem most likely to be compatible, but there's not a lot of documentation on the former.
