Unfortunately I do not have pics of the SkyCarbolite I mentioned. It was like this, but with blue bits allover.
A red/black metallic in the front triangle and a ti rear. The bike looked both expressive and classy. Imo aesthetisly still one of the most pleasing bikes I've ever owned.
Another red/blue bike I would like to own:
3D Racing Rover by Chris Herting!
I think in many cases blue bits on red frame don't work out great. Though I do not think it is an absolute fact red can't go with blue. Exceptions excist ...and can be even more interesting because it isn't the obvious/logical choice.
Also don't forget our nations flags are in red & blue
Turns out great, right.
