I had trp spyres(road bike version) for years on my cx, super easy to set up,way easier then bb7s. Used both road and mtb versions. Never had an issue with bearings. Only thing I didn’t like was the pad adjusters would shake loose over time. Easily solved though. Biggest issue is they cost about the same as a really good prebled set of hydro brakes. Not sure I would get cable brakes when a set of m6000 arent much more in price.
I switched my bb7s on my mtb recently to Hydro Deore m615. Work great for me. I’m around 210lb and have no issues stopping, great modulation, easy setup and install/bleed. I put them on and took about 5 minute to bed the pads and was in the trails. They were a lucky find, oem takeoffs I picked up for $100.
