I've recently swapped my Shimano 10sp (11/25) cassette with a HG500 (11/34) to try and help on the climbs.
After swapping the cassette I now understand that I also need to change my rear derailleur (currently a Tiagra 4600 short cage).
However, I'm struggling to find one that is compatible with the HG500 cassette and Shimano STI 4600 shifters I have.
Does such a thing exist or do I need to look at changing more of the setup?
Thanks for any help.
You might be able to extend your current derailleur with a hanger extender (search wolf-tooth road-link then find a cheap Chinese substitute if you prefer). Or you may need a longer derailleur for overall capacity.
