Thanks william Yes I have a brifter. I probably did say all the parts were worn out- what I mean where the cassettes and chainrings. I was trying to figure out how much weight I would save by changing to a double , then I got all side tracked wondering how much better the bike could be for not too much extra cost. One lb is not that much and it does add a lot of cost to redo the whole thing unnecessaril.
