I have an old Bianchi and am not so much interested in keeping it in vintage condition as much as keeping it working. The brakes need replacing. Because if its vintage, the brakes and levers pre-date dual pivot (does that make them single pivot?). I have a line on a relatively new set of Tektro R312 for very little money but they are dual pivot. Must I switch the levers too or will my current levers work?
