Boas!
Grande Novidade no campo das Biclas :D
A Shimano vai introduzir em 2009 um conjunto de manetes de travão e mudanças (e desviadores com motor electrico) no grupo 7900 - Estrada como upgrade, não sendo necessário comprar carretos, corrente nem cranks, movidas por uma bateria não sendo necessários cabos!
Japanese parts manufacturer Shimano is launching an electronic shifting system for high-end road bikes that it claims will vastly improve performance and reduce maintenance. By replacing the conventional levers that pull wound-steel cables through protective housings with solid-state switches and rubber-coated wires, there's no chance for road gunk to clog things up and interfere with shifting, or, for that matter, your post-ride beer.
Shimano plans to offer the electronic setup as an upgrade option within the 7900 group -- which is preselling for $2,600 -- so parts such as the two-tone cranks and brakes will be the same. (No word yet on the additional cost for electric; it could be double.) Di2 consists of two brake-and-shift levers, two derailleurs whose springs have been replaced by servo-motors, a 7.4-volt lithium-ion battery pack, and the wiring harness that connects everything.
