I’ve had BB5’s not much power and the pads are a pain in the arse to change and the adjusters seized up and the metal is quite soft.
I’ve had BB7’s much better power but went hydraulic
Then had the TRP Hyrd, but the lever pull was massive, as in going down a steep hill with the lever touching the bar and still not stopping. It may have been my step up but it is really difficult to get the exact cable tension.
Now got the cx77, with ice tech rotors. No problems at the moment apart from the pads it comes with don’t last long. The pads are the same as the mtb brakes so easy and cheap to replace. Power is good and adjustment is easy.
