I need to improve stopping power on my old Paramount as I live in the Foothills and do a lot of descending. I'm hoping to replace the Campagnolo sidepull brakes with the Tektro double-pivots with 73mm reach. However I can only find them with the sleeved hex-head mounting nut. This isn't compatible with my old frame. Would I be a blasphemous fool to drill out the Paramount? I guess the alternative would be to get some stupidly expensive Paul Racer cenerpulls. Thanks for your help.
