Campagnolo's arsenal of time trial equipment includes these Alloy TT Brake Levers. They're designed to be installed in the ends of any modern time trial or bullhorn base bar. They offer a sleek aerodynamic profile along with a functional detail that Campagnolo brake users will appreciate. Like their Ergopower levers, they have a tension release on the lever to open the caliper and facilitate quick and easy wheel changes. Another detail that we really like is that the levers have torsion springs that keep them snug and rattle-free rather than relying on the tension in the cable system to do the job (in our experience, it never does). This way, all you'll hear as you enter your personal world of pain is the wind whistling over your helmet and the whoosh whoosh of your disc wheel on the pavement. The Campagnolo Alloy TT Brake Levers are right and left specific. They're marked on the brake tension release button. They come with Campagnolo stainless steel inner wires, housing, and ferrules.
