I’ve had more problems with my disc brakes then I ever did with callipers, and I’ve only been on disc’s approx 4 years.
I’ve just put in another warranty claim on the RS505 shifters, this is the 3rd time in 4 years I’ve had the gear cable cut into the shifter. The current trashed shifter is only 4 months old.
I received 105 7020 as a warranty replacement in Nov 21, but it’s taken till now to source the callipers and hoses thanks to parts shortages in the UK. Hopefully these don’t have the same problems as the RS505…
I need to rely on the LBS whenever I have a problem too, whereas with callipers I’d happily do all of the work myself.
I will say though, in the wet they are a godsend. Callipers will work in the wet, but there is always that seed of doubt in the back of your head whenever you REALLY need them. I wouldn’t commute in the wet on anything else.
