However, mid-range and entry level will likely still support rim brakes (and cable shifting) for quite some time.
for sure and I hate to think that, technology-wise, they would just stop any future development for rim brake, not that there's anything wrong with the current dual pivot caliper, but could it be better? or even lighter?
I haven't seen any pictures of Sram Red eTap AXS rim brake version but I would guess it's using the previous generation caliper.
Not to mention development for brake track on wheelset would also stop.
