David,
I have not heard many people challenge the claims of others quoting 7-11 watts from a chain only. I'm sure there are people questioning that claim, I haven't followed the threads. But based on the 2% concept, that would suggest an extremely high power output which is not within the grasp of anyone over a 112 mile bike, let alone a 56 mile bike. Of the pros I work with, over a 112 TT the highest power I know about is in the 320-325 watt range for the effort. Based on that, if we go conservative and assume a 7 watt savings, that is well over 2% and the chain does not account for 100% of the losses.
I know the testing protocol used when our products were tested and I know what we have done internally, and am confident in our numbers. What others test, claim, etc...I haven't a clue. I also know that we have a very deep repeat business in many forms of motorsports that have used our products for over a decade in NASCAR, IndyCar and many forms of road racing.
Best,
Andy
