I have 9 speed, Flight Deck compatible, 105 STI shifters. I like the idea of going with a FlightDeck computer, but I'm not sure which harness to buy. I'm looking on ebay and want to be sure I buy the right one. My shifters are model ST-5510, there is no "c" after the numbers. It is a 9 speed, triple set up.
Can I use any of the 9 speed harnesses for these shifters or are there specific harnesses that work with these units and others won't? I'm just plain ignorant when it comes to Flight Deck.
Thanks for all help.
