The evolution of famous Superzero stem designed to allow a fully integrated cable routing when assembled with Deda handlebars featuring the DCR system (Deda internal cable routing). The Superbox stem features a proprietary system that provides two possible mounting solutions for the internal cable routing. The complete internal cable routing (DCR)* or the semi-internal cable routing (S-DCR) through a cover that allows the installation, adjustment or service without unnecessary complications for electronic cables and hydraulic housing disconnection. Superbox works with 1-1/8" standard fork steerer, the stem is compatible with a 46 mm (for 1-1/8” bearing) or 56 mm (for 1.5”bearing) upper headtube. The stem package includes special spacers that provide the channels for the housing cables. Spacers and the nylon cover are designed with slits that let them pull open, they can be added or removed to get the fit right without having to remove all cables. The innovative 3D forging technology and the flat design result in a better aero performance. The Superbox stem is offered in different lengths from 90 to 140 mm to enable riders to find their ideal riding position. The nylon cover, the integrated topcap and headset spacers, the 46 & 56 mm topcover complete the line of accessories included. * In case of bicycle frame using D-Shape fork.
