Been thinking about switching from Aluminum to a lightweight steel frame for more long range comfort. I'm interested in the Salsa Primero 3 lb steel frame. Anyone ride one of these? Haven't found much info on the net about them. They are about the same price as a comparible all carbon frame (Giant), but I like the idea of having something a little different, not so mainstream. Any other steel frames of this weight range I should consider? I'm coming from a 2.5 lb Aluminum frame, so I'd prefer to keep the weight difference in check.
