This clamp fits around a 1-3/8" (34.9 mm) or 1-1/8" (28.6 mm) frame tube and adds a cable housing stop to frames that don’t have one. It’s perfect for adding brakes or derailleurs to a vintage bike, fixed-gear frame or converted single speed, with no brazing or frame modification needed. It installs in minutes and gives you clean, precise cable routing.
