will the rd-5701 105 work with my current set-up
I have a trek 1.5, so currently rear derailleur is tiagra. I run a 50-34 compact (upgraded from standard FSA Vero to 105 chainset) at the front and 12-30 cassette.
I think I should be fine to get this rear derraileur to replace the standard tiagra one that came with my bike, but just want to check I'm correct (basically I want this one in particular because it is black, rather than current tiagra one being silver!!).
If indeed this is fine - do I need to order a specific one (i.e. gs or ss) or should both work with the set-up?
