Currently thinking about a new frameset, primarily for randonnees (including PBP 2019) and touring. The big decision is what size tyres to run, and thus what brake calipers to use; I've decided to stick with rim brakes. Cantis are an option for wider tyres + fenders, but the Racers are a bit neater and I have a set I could use.
Note that I have MTBs so heavy offroad use isn't likely.
Any suggestions or data is welcome.

Most of the time BSPs or Hetres will be used, but it would be handy to be able to use something tougher in bad condutions (like the Marathons), or bigger for dirt - largely to lift the BB a bit.
Thinking aloud, it might be sensible to use a MTB crown + cantis for clearance and versatility. Seems like clearance at the rear may be easier to achieve, given the bike will be using 2x11 with small rings, probably 44x30 max.
Anyway, no need to decide until after trade show season, just in case something changes the rules again. :-)

Thanks Philip, just the sort of info needed; I hadn't thought about the sides of the tyres rubbing on the calipers. Cantis are looking more likely all the time, and I could always repurpose the Racers (maybe for a conversion), or sell them.

Thanks Rob,
It looks as if the only way to figure this out would be to obtain samples of all the potential tyres and check each one. That could get expensive very quickly, whereas cantis would definitely clear. They have their own set of problems though. Might be time for me to order a couple of tyres and find out for sure.

Huh, that's interesting. Just checked and my Racers (centre mount, not braze-on) allow a Soma GL tyre through when the QR is undone, though the pads do touch. And that's with the thicker toe-in washers on the inside of the arms; if these are swapped around the pads clear the sidewalls by a mm or two.
As I don't have a car this wouldn't be much of an issue for me anyway, and no way I'd carry a floor pump on the bike. :-)
