after talking with a track racer in portland for a bit and watching footage, i've decided i definitely want to start track racing when i move back to portland. so, my question is, as a beginner, what do i need as far as bikes are concerned? one bike i really like is the iro angus ( http://www.irocycles.com ), but i'm not sure if that'd be a good bike for someone like myself to begin on. i also hear a lot of talk about the bianchi pista, and i guess that's an option, too. but i'm not sure what else outside of those for a beginner's bike. any suggestions?
