With CNC machined alloy and carbon construction, and weighing a very competitive 180g, Dia Compe's Gran Compe Zero is a competent and good looking alternative to Shimano's Ultegra and Dura Ace mechs. It's also compatible with, Shimano’s 10-spd Dura-Ace, Ultegra and 105 transmissions and it's SRAM compatible too according to Dia Compe – though not with SRAM's 10-spd lever – which doesn't make it sound like a definition of compatibility to us.
