I should be receiving a Technomic stem this weekend to replace the steeper quill and am really eager to start riding again. My current setup is Campy Veloce 10 speed levers. Is it possible to simply remove the levers from the handlebars and swap stems? Or will I have to uninstall the cables from the levers and then reinstall?
Assuming you have enough slack in the cables, you should be able to just slide them off your old handlebars after you unwrap any tape on the bars. I've done this with Shimano 105 levers without a problem. The only thing I had to do was undo the little tightening nut on the front brake hanger so I had more slack in my front brake cable.
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
Pull the lever and look inside the gap. You should see either a slot head bolt or, more likely, an allen head bolt behind the cable anchor. You loosen that bolt and the lever should slide off. You may have to remove the cable to get to the bolt but that's not always necessary.
