My swop to road discs was based on regularly descending a local hill…found consistently faster and happier on mtb
…long single lane rd with unmarked junction at bottom and a bridge that could only see on coming traffic very late…on road bike always scared of grabbing too much brake…know shouldn’t but for me easy in an emergency speed kill…mtb with discs more modulation more confident could safely kill speed…so discs it was for me with the benefits of wider tyres and not checking rims…
