• Ok. You don’t think I can just whip the post-mount calipers off the ends of the hoses and replace with flat-mount versions? Appreciate it would cost more to buy new calipers….guess I was wondering if there’s any issue ‘built in’ to the shifters themselves, or do they just push fluid down the hoses so it makes no difference whether post- or flat-mount calipers are at the end of them?

  • Yeah it makes no difference. I put my girlfriend's existing 105 FM calipers onto a set of BR785 brifters that came with PM calipers and then sold the post mounts. Super easy.
