看SRAM网站怎么解释的吧。其实不用表述得这么复杂的
1:1 Actuation™
1:1 Actuation™ is simply superior. The very nature of its design makes it this way. For every 1 unit of cable pulled or released, the derailleur moves the same amount. Simple? Yes. Dependable and tolerant? The best. Ease of set-up and adjustment? Easiest. This is why the top athletes in the MTB world prefer SRAM. From the mud infested Cross Country of the Sea Otter Classic, to the rocks and roots of a Fort William World Cup Downhill the 1:1 actuation stays precise and fluid. 1:1 Actuation precision is why you find SRAM on the elite bikes from cross-country flyers to full gravity bombers. 1:1 • Setting the shifting standard!作者: cam 时间: 2009-8-24 13:07
