Local bike shop...try venturabicycles.com for one I know he has em.I was checking out your builds on your webpage - very cool.
Can I ask: Where did you score the curved seat posts?? Did you make them yourself?
I saw two different kinds - one on a trike, and one on the bike with the saddle bags>
I cannae find anything like them online, not yet anyway. Did they need extra support to be curved back like that?
Cheers
