I'm thinking about switching from riser bars back to flats...I like the layout of my cockpit right now, but I'd like to add bar ends, save weight, and get a slightly wider and slightly lower front end. Has anybody made the same switch, while keeping their front end from dropping too much? I don't want to slam my front end in the weeds like an XC racer, and my current setup is a 40mm rise bar and 6* stem. Can I switch to a higher rise stem with flat bar and stay similar? What rise will I need?
