I got these brakes on recommendation from a bunch of trusted bike friends to replace the absolutely **** stock brakes on my 2023 Topstone 4 (the stock brakes are Promax 330Rs). I got the flat mount and they fit perfectly on my frame with the adapters. Adjusting them was not too bad. The two-piston design really does keep the rotor from flexing when you squeeze the brake, which makes it easy to center the caliper properly. The barrel adjusters work smoothly and easily.

My one complaint about these brakes is that the pad adjusters are *very* difficult to turn. They require a 3mm hex wrench, but the actual bolt the wrench turns is sunk down pretty deep into the body of the caliper, and it's just about impossible to actually get the wrench to seat in the bolt correctly to turn it and adjust the pad. Most of the time I spent futzing with these brakes after installing them was cursing at the pad adjusters trying to get the damn wrench in there to tighten up the pads.

These were awesome. I put them on my go tracks GX2 because the brakes that came on that were noisy. These decreased the stopping distance and our significantly quieter.
