Ok I have an 07 schwinn fastback sport that some had changed over to bar ends, a deore rear derailleur, a random front derailleur, and a 6 rear cassette. I want to put brifters back on it. If I changed the cassette back to an 8 speed and made it a single front chainring what all would I need? Don't worry about front derailleur as wouldn't need it. Would the rear work? Just buy a single shift/brake lever (right side) that is an 8 speed compatible? Or what is your guys ideas. I'm just worried about buying stuff and it doesn't work. I want to do it myself so please no lbs as there isn't oNE within an 1.5 hr from me.
