Hey all. I've been mountain biking for awhile and want to get a good bike for the road. I have the option to get a Bianchi vigorelli that's a couple years old for $1000, a specialized allez comp 08 for $600, or a khs 300 or 500 new for $700. If anyone has any experience or advice on these bikes or other good bikes for around the same price I would really appreciate any feedback, thanks.
