Rim brake with 32 mm tyres

[SSCC]

There don’t seem to be a lot of rim brake frames that can fit wider than 28mm. Are you riding a rim brake bike with 32mm or wider tyres? If so what frame and brake calipers are you using.

The Shimano R8000 comes to mind, they are set to handle up to 28mm RIM width, my understanding is that the ID of your rim also has a bearing on the final effective width of the final inflated width of the tyre though as is the height of the brake caliper on the frame. 
Some discussion links but I would be keen to hear some local user experience

I struggled 28mm tyres on my 2013 Giant TCR - more at the rear because of the brake arch clearance due to the height of the tyre.
The front was less of a problem.

Also, getting the wheels on and off was a mission because the brake calipers didn't actually open wide enough. This made me think that my bike was old and wasn't designed with these fat tyres in mind.

Shimano did have a tall version of their caliper brakes:

I don't understand how those would have helped as the mounting bolt on the frame dictates where the brake arch sits.
Or, maybe they just opened wider.

I’m riding Spez Roubaix 32 tyres on my Cannondale Supersix EVO, 2019, rimbrake. frame clearance is ok, but Dura Ace brake bridge has about 2 mm clearance, so with stiff wheels that’s OK.
I Just don’t use it in too much rain or mud.

I also had that 2mm clearance on my tyres, which nearly ended my DC because of a tiny stone that got wedged in there and started cutting the tyre.

Frame clearance at the chainstays was also tight, so a slight bubble in the tyre or mild wobble in the wheel needed swift attention.

Frame clearance and then brake caliper reach is the key problem with fitting 32mm tyres to a rim brake frame.

long reach calipers are necessary

28mm gp5000 are actually like 30mm+ in true measurement so you just go with that.

with what internal rim is that? does ID not have a bearing as well?

Yeah internal width makes a huge difference. I have some 42mm tyres that measure 48mm on a 28mm internal rim.
