- spectramax 7y agoI presume 2% efficiency means is a difference of many seconds in competitive cyling. It is huge. When I used to work at GE Gas Turbines, a 2% efficiency increase from generation to generation would destroy the competition (Siemens). It could mean millions of dollars of profits for energy companies that run these turbines 24/7. Not saying its the same thing, but 2% efficiency increase in most highly saturated markets such as LEDs to cyling to wind turbines - is HUGE.
- pmontra 7y agoIf UCI allows it on race bicycles and I if it can survive real roads everybody is going to use it in races no matter the noise. 2% is huge. For amateurs doing races, it's the same. For the huge majority of amateurs it depends on cost, durability and ease of maintenance. For everybody else, it's only the cost.
- loeg 7y agoCan you imagine taking a dinner plate of shark teeth rotating at ~20 Hz in the calf? I kind of doubt UCI would allow this on race bikes, at least uncovered.
- skykooler 7y agoOn the one hand, it's a 2% gain in efficiency. On the other, it's a 60% reduction in losses. From that viewpoint, it's pretty significant.
- loeg 7y agoDrivechain losses only, and only if you take their numbers at face value. And if you ignore losses due to shifting. There are plenty of other losses (aero drag ...).
