Anyway, I can confirm that Juin Tech R1 is much stronger than TRP Spyres. After the upgrade I have the stopping power from the hoods I had been missing before. I am not saying that Spyres or BB7s are bad, for me some advantages of Juin Tech R1 are:​​​​​​
  • Better stopping power, need it as a heavy rider.
  • Hydraulic system will re-center automatically, very convenient for the QR wheels I have on the Double Cross.
  • Adjustment for pad wear is done with one knob. With Spyres I had to drill a hole in the dork disk for the 3mm wrench to adjust the pads. Also, these adjustment screws would loosen, making me re-adjust them periodically. Purple Loctite (kind of) fixed this.
  • Slightly shorter lever throw, easier to setup.
  • No sophisticated mechanical parts which can be contaminated with dirt.
Not sure about oil boiling on long descents, have not tried that. Spyres and BB7s win here. :)

I don't believe recentering is correct, none of the hydraulic calipers can recenter since the caliper is not floating(like a car caliper). They have automatic pad advancement but if you swap between wheels you have to reset and recenter each time with any hydro system if the rotor location differs significantly

Got me!

Yes, saying "it will recenter" is not right, what I meant is that one of the pistons will extend further making the pads recenter on the rotor. On TRP Spyres this was done by adjusting the pads using a 3mm wrench.

Another thing I like about Juin Tech is that it uses Shimano A-type pads, which are narrow profile as opposed to the wide profile B-type used by Spyres. This makes it compatible with both wide and narrow profile rotors.

So random update: I swapped my older TRP Spyres for some TRP HY/RDs. Only changed calipers - the rotors and cable housings stayed.

What I expected was that there would be less friction/resistance in pulling the hydro lever on the HY/RDs than the mechanical lever on the Spyres. I was right. They feel really nice and they give me quite a bit more control when trying to modulate the brakes over technical riding.

These are being paired w. the Sensah SRX Pro levers and they work very well.
