This is a great discussion, guys, thank you for the dialogue! I'm happy to clear up a few of these questions.
First, a realistic test would absolutely be conducted with intervals, cooling periods, speed variance, caliper force variance, etc. We mimic real world conditions in our internal prototype testing. That is how we first developed these rims! For this test, however, we simply wanted to design a protocol that would allow us to directly compare the failure modes and properties of carbon clinchers. Nothing more, nothing less. You can interpret the results however you wish. For us, we have found that the results are directly proportional to the long term durability of the composite. You probably won't brake for 5min down a steep hill during your first ride on some new wheels. That's unlikely. But you may reach the resin glass temperature for 5 seconds ten times per week for many years. Cyclical loading of the resin will respond just like cyclical loading of any material - it begins to break down. The rim will slowly start to deform and pulsate under braking, and will eventually fail if it isn't caught. That's how most rim failures occur. The goal of our new rim project, and the test, was to see how we would compare with our competitors in overall durability and create a product that would dissipate enough heat every day to keep the resin from seeing long term effects.
Of course there are metrics that people still want to see. We can only test so many variables in one study, but we will have more tests to present to you guys soon! The more data the better. But it's important to note that the heat buildup in the Alto rim was dissipated faster due to the resin properties, not a lack of friction. This can be seen in the phase 2 test, where the total load and friction were greater than other rims (i.e slower rim speed before pad glassing) but the temperature remained lower. Also keep in mind that the total amount of energy into each rim (for phase 1) was identical, as it includes the kinetic energy of the spinning wheel. The equation would include the motor input, caliper force, pad/rim friction, and rim speed. A rim that sees more friction due to the textured track (like Enve) will spin slower, and the energy dissipated by the rim will be identical because it must reach a 1200W equilibrium. The amount of that energy converted to heat has to do with the properties of the composite and the resin.
I hope that helps to clear up some questions, although it may create more! Either way, I'll check in and respond as much as possible! Thanks again for the discussion, that's what it's all about.
As others have said, you need to re-do the test using manufacturer's recommended pads. And if the price of durability/heat resistance for some rim + pad combinations is inferior braking performance then you need to measure that. It's disingenuous to call out a "failing" of a "system" that isn't in fact the manufacturer's recommended system at all.
If you do this testing, and your rim is as/more durable as others', and you have better braking performance, then you have a real winner
