rear caliper with best clearance?

They look like it. forum members at weightweenies suggested them as well. they are $$$ though and difficult to find a pair to "test"

I wish I was working with that much clearance!

I think shifting your 28c tires to a wider inner profile rim, such as a 20-21mm, (given my current readings) will lower the overall height of the tire a bit...but not much. It will also improve your contact patch, give the tire a better overall profile and allow you to run lower pressures if desired.

my problem with the Record caliper is not side to side, but overall height clearance.

My problem is with the height clearance as well, not side to side.

Finally resolved this issue.

Installed a Dura Ace 7900 rear caliper. Loads more clearance at the top of the tire (almost 4mm) and side to side than the Campy Skeleton SR single pivot rear caliper. Consequently, much better braking power and modulation as well. Still not enough room to run 25c, but I can live with 23c for now on this frame.

These are Ultegra 6600 with schwalbe marathons in 28.

I was testing my clearance on this frame to see if I could go 25 instead of 23. 28’s are too large for this!

i wonder how good the newest crop of campy brakes are? i think one of the design goals was to maximize clearance.

i guess we will have to see once they start appearing in the wild.

Would you have enough clearance to run something like this reversed, pointing up? Simple to cut out of some Aluminium and would likely allow you to run your Campagnolo SR11 callipers and 25mm tires. Image borrowed from the internet.

The BR15-CHDP brakes (2015 CHorus Dual Pivot) made in taiwan on the right in the picture made a huge difference in gained vertical clearance front and rear versus the 2011 made in italy design on the left Despite campy NA telling me nothing had changed you can clearly see the pivot location changed. (the DP on the right is lower)

This was my first thought; the EE’s have pretty good clearance. The very latest record/super record also seem to have better clearance.

Both of these options are expensive, so it would be good to try before buying.

Dura ace 9100 have tons of clearance too. Not as much as ee but enough for me to get tires that measure out close to 30mm to fit.

Wish I woulda known this!

The frame is currently parted out and for sale, but I also wish I'd have though of using one of the Cervelo aero rear brake tabs to try and relocate the caliper...bet that would have worked nicely:
