Anyone know anything about disc brakes?

Haha no. I started reading that and got as far as this:

"Spyre is susceptible to water ingress that causes friction in the operation of the brake over time due to the ball races becoming corroded. Salt and mud is an issue. I think most cable disc callipers suffer the same. Certainly had more than one BB7 seize on me due to lack of maintenance.

I was probably the first to experience the issue with the ball bearings coming out of their cams due to excessive pad wear that led to the recall. At that time I contacted TRP for a guide for stripping the calliper but was informed there was not one."

Cantilevers can be easily cleaned and serviced in a few minutes time. The above passage confirms to me that discs are not what I want any more. I'm not saving any money on rim wear, I could have replaced my rims twice with the amount I've spent on pads and cables trying to get these to work. Not to mention the time wasted. rant rant rant...
