As above, I require one of these please.
I purchased one of the newer Tiagra rear mechs only to find out they have changed the cable pull ratio slightly since the 4600 model so it's not compatible with my shifters :(
For those shifters you can use any of the
7/8/9/10 speed Shimano RDs up to and incl the 4600/5600/6600 series, the pull ratio remained the same throughout (aside from the Dura Ace 7 and 8 speed) all the way up to the internal gear cable/later 10 speed series as you've found.
I've actually got a NOS/bike pull 7 speed RSX (off a mid 90s Peugeot I had) that should work.
it has a replacement nut/washer on the cable retention bolt and a small mark on the rear plate but is otherwise unused.
Has a nice 5700 which will be compatible
Thanks very much for the info! I’m gonna try this one above first as it suits the more modern build it’s going on
No worries if thegreatbelow goes for that but I thought that the hidden cable 10 speed gen had a different cable pull that isn't the same as the 4600 series and other non hidden cable shifters?
6600 is fine, 6700 is different
Hmmm, maybe - I know 4700 is different for sure. In real terms however, know loads of people who've used 4600/5600/6600/5700 mixed up in every combination possible without issue. Someone on here will know better mind.
Best of luck
I know, hence why I mentioned it earlier in response to Pasty and so to prevent the OP from buying a mech that doesn't really match their shifters. 5700/6700/7900 has a different cable pull so as per what I said in my first post any of the early non hidden cable 10 speed series work as does anything else before that all the way back to 7 speed except the DA 7/8 RDs.
If you're still looking, I have a Tiagra RD-4601 in good condition.
I am sorted now thanks.
