    Thanks for all advice guys, I
    Thanks for all advice guys, I have decided to go with the Ultegra RD5600 short cage after all your advice. ProBikeKit has advised the same with the limit screws. Hopefully I can live with until I can upgrade my STI’s to 10 Speed. =D>

    OK, haven’t tried a 5700
    OK, haven’t tried a 5700 series mech on 9 speed (i have one in a box so I might try it out and check) but I’m surprised it’s so different from 10 spd 5600. The difference in width between a 9 and 10spd cassette is no more than 2mm.

    Shimano Tiagra HG50 9 Speed
    Shimano Tiagra HG50 9 Speed Road Cassette is now available for $16 at chainreactioncycles.com. I’m sure there is a similar price in the Brit Isles somewhere

    The 5701 10 speed will not
    The 5701 10 speed will not work with a 9 speed cassette. The limit screws don’t actually go far enough to let you get all 9 gears. The 10 speed is a narrower cassette surprisingly. I found this out the hard way. Even removing the limit screws doesn’t give you more than 8 cogs and a rattle against the 9th. Fortunately for me I built a 10 speed drive train not long after, but no the 5701 won’t work.

    Tiagra or Sora should be fine though. The current TIagra derailleur is basically the old 9 speed 105.

    how’s that? I’ve been running a RD-5600 on a 9 speed cassette for about 3 years, it’s never been a problem.

    yes it will. 9 & 10 speed
    yes it will. 9 & 10 speed derailleurs have the same pull ratio, 11 speed is different.
