NOS Flight Deck install not recognizing 53T chainring
Today I hooked up some NOS FlightDeck wiring loom and head unit to some Dura Ace 7800 shifters.I got the head unit programmed for the 53/39 chainrings & the 12-25 10 speed cassette. Everything went together pretty well and I was really stoked today when I was thinking that I would have another bike...
