在补几张图以及实验室的测试数据。
CeramicSpeed的测试表明，典型的Dura-Ace动力传动系统的峰值效率约为98％，而CeramicSpeed的优化版本为98.5％。我们真的在谈论增量收益。新的Driven系统在同一测试中实现了99％的效率。当你开始添加诸如链润滑油降解和交叉链摩擦之类的东西时，传统的动力传动系统会变得更糟。那些高峰数字？这是平均功率输出约500瓦。如果你没有发挥这种力量，数字会变得更糟。在200瓦时，DA约为96.75％，优化版本为97.75％。Driven系统的起价为98.75％。将数字换成另一种格式，他们说250瓦时，Driven的摩擦力比CeramicSpeed优化的DA传动系统少32％，摩擦力比Dura-Ace库存少49％。

CeramicSpeed’s tests show that a typical Dura-Ace drivetrain’s peak efficiency is around 98%, and a CeramicSpeed optimized version of that is 98.5%. We truly are talking about incremental gains. The new Driven system achieved 99% efficiency in the same test. When you start adding in things like chain lube degradation and cross-chain friction, things get worse for the traditional drivetrain. And those peak numbers? That’s at an average power output around 500 watts. If you’re not putting out that kind of power, the numbers get a little worse. At 200 watts, DA is around 96.75% and the optimized version is 97.75%. The Driven system is up at 98.75%. Putting the numbers into another format, they say at 250 watts, Driven has 32% less friction than the CeramicSpeed optimized DA drivetrain, and 49% less friction than a stock Dura-Ace group.
