To me, the disc brake debate is way more polarized than it needs to be. Seems like you either have to be all in for team rim or disc and completely ignore the drawbacks of each.
Froome had a very balanced take, and while I am a proponent of disc brakes, I agree with many of the points he made. I have had consistent issues with rotor rub particularly in the front. Hydraulic in particular is a PITA to work on and much less efficient than just adjusting some cable rim brakes. For the average person, the cost of the gorupsets and wheels are higher. That said, I would not want to go back to rim on the road bike. The consistency of braking is so much better on long technical descents we have in the NC mountains. They may howl but they do work in the rain. My opinion might be different if I were a pro racing on closed roads needing to save every gram.
Now that said, I still have a rim brake TT bike and am very much on the fence about eventually upgrading to discs. I see no need to for 95% of TT applications- but it would be nice to consolidate down on my wheelsets and components. Sure you don’t need brakes most of the time on a TT bike, but usually when you need them, you REALLY need to stop. The rim brakes on most TT bikes are frankly frightening in those scenarios.
