For a 20mm wide rim do I go 19 or 22 tubs?

Rule of thumb: for aero 19mm / for lower rolling resistance 22. BUT it's impossible to tell without knowing the brand (tire / rim), course you want to use them on. Even with specifics it's a guess.

The rear currently being 25, a front 22 will look slightly less nuts. If I swap for a real disc wheel at the rear with 22 or 23 a 19 front won't look as odd. Conti comp or tt tubs.

I thought it's about speed and not look.

Ah, ah, I'm an artist first. Shamal isn't best choice for aero but gold suits the idea. I guess I'm going with 19 since 22 is only available in schwalbe one at a good price. Conti tt or competition. Between the 2? Atlanta gold would match even better but I'm actually riding this so it can't be 100% nuts. Crap, I probably shouldn't say that. :lol:
