Polo Bikes

I think hija and triton are just frame builders who will do what you send them (although I've heard some of the hija's arn't exact spec... But they are the cheapest option).

Marino is the only one where you are paying for a specific geo, but they are made by hija, so it's his design which he's being paid for, so I doubt he'd happily share the angles and lengths.

Marino is the welder, Hija us Alejandro's brand.
