Juin TechGT-P Cable Actuated Hydraulic Bicycle Bike Disc Brake Caliper Set Extra Powerful Hybrid Brake for Road/Mountain/Cyclocross/Gravel/E-Bike/Folding Bike etc. use(Black)

I just put these on in the past couple weeks, so early evaluation. Replaced TRP spyre mechanical. I ride gravel and passes on forestry roads in the Rockies, fairly steep sustained downhills. The mechanical had good slowing but not stopping power. The Juin have much better stopping. They are a lot more break. The caliper are larger. I had to go to a 180 rotor on the rear to give the caliper enough room to clear the frame on a Salsa Fargo.The modulation and feathering isn't as good as standard hydraulic trail bike breaks. They are not as strong as xt or codes, but they are a lot more break than mechanical cable.If they hold up I'm happy. They do seem solid enough. I call them legitimate.The last Pic is trying to compare size of the Spyre to the JuinHappy riding

These Calipers are as described and and are very well made. They have not been installed quite yet but seem to fit well on my in process electric mountain bike.

I will change my review after replacement. Never got the chance to use them. As soon as they were installed I noticed something was wrong. I never tried to adjust them or get to ride the bike at all. Actuator shaft was broken. I'm actually having high hopes for these calipers. They are going on a heavy ebike. I hope it's a fluke. I'll find out. Hopefully not with a crash.
