ultegra RD-6500-SS as good as DA RD-7700-SS?
Hi..im new to here and im looking forward to replace my 105(triple chainring) rear derail. The local shop offered me about $86 USD for DA rear derail and $47 USD for ultegra. I already read some reviews at roadbikereview.com but some of the reviews saying this derail isnt as good as i was expecting. The price differences are huge in my country's currency. For me, i`ll choose ultegra but will it perform as good as DA? By the way, does STI makes the different in shifting as well? Im using DA 9spd STI and maybe using DA rear derail will give any advantages??
