My Dyna Tech's mech hanger (non-replaceable, of course!) has a chewed-up 'stop' at the bottom, which is there for the B-tension screw to press against. The screw slides straight down instead of pressing into it. Anyone have any ideas? I've been thinking about fitting a nut on the end of the normal tension screw (or putting a socket-head bolt the wrong way aroun) so that the larger head hits the stop but I still don't think it'll give that reliable a contact.
On my road bike I've got a SRAM rear mech and on that design the tension screw presses into a stop that's built into the mech, and then a larger portion of that fits the shape of the hanger stop, so it looks like there's a much larger surface to contact between mech and hanger. I'm pretty sure that would do the trick, but are there any Shimano-compatible mechs that use that kind of design? On the Dyna Tech I'm currently running a Shimano 9-speed mid-cage rear mech (for 22-32-44 and 11-27). I don't mind switching the mech to fix it but I could really do without switching the STIs over to SRAM as well...
