The Deda Superzero Clip-On Extensions are built for riders who want a genuine aero position without committing to a dedicated TT cockpit. Precision-forged from 6061 aluminium alloy with a black anodized finish, they clamp onto standard 31.7 mm handlebars and bring your road bike into time trial and triathlon territory — without the drama of a full cockpit swap. The armrests use Lycra-covered foam pads to take the edge off long efforts in the aero tuck, and extension length is adjustable to suit your reach. A nylon bridge ties the extensions together and adds stability underway. At around 330 g for the system, the weight penalty is minimal for the aerodynamic return.
