my only question is whether the small amount of hydraulic fluid is prone to boil under heavy load in prolonged use.

It’s working well for us. It’s got good stopping power. We can lock the rear wheel with just the rear brake, and modulate short of that. So it’s got plenty of stopping power.

I totally agree about the Spyre. I found it to be okay for the front brake but inadequate for the rear. Since I was unable to mount the HY/RD on the rear, I went with a Paul Klamper disc brake, and it was a huge improvement. They're just a bit on the heavy side, though.

Carbon Composite max working temperature
I work for the world's largest CF composite supplier. At 180 degrees C rim surface temperature, the resin holding the layers of carbon together on your rim is beginning to carbonize. Go above that temp and you are no longer insured.

I used to ride clinchers on the tandem. I blew sidewall off Mavic Ceramics - twice. Last 20 years I just use tubulars.
We have dual Enve rims 24/20 with Vittoria Corsa 28 rear and Veloflex Vlaanderen front.
