Hi all!
Been running a Challenge Getaway 36mm tire on the front and a 36 on the rear... but it rubs a little at 40psi. I'm swapping it for a 35mm terra speed - which I understand measures narrower, around 34 rather than the 36.8 the Getaway measures on the back. I can't stand up and ride with it without it rubbing right now, which is annoying.

My question is, anyone riding a 650b on these? Or potentially a 650b rear only / mullet setup? I think I could get a 40mm on there with a 650b tire. Definitely could do 40mm on the front with a 650b, 40mm fits fine width-wise but rubs on height.

Another question - I think a 40mm tire with 650b wheels would only be about a mm or two smaller in diameter as the tire will be a few mm taller.
Basically, I'm new to gravel (could you tell) and would love some advice!

TL/DR:
Anyone running 700c front 650b rear, how do you like it?
Anyone riding a SSE4 for gravel?

Cheers!
