Onza fixed wheel

We are always interested in Niche products but as pretty much newcomers to the wonderful world of fixies, we haven't a clue what Polo specific products might be. If you can flesh out your question with some more specifics and details we are happy to look into it.

The main stuff people would be after would be burly frames/forks and very low geared drive trains.

Where are you based? You should come down to polo one day and chat to people. I know that BAD are (allegedly) getting custom polo bikes built by their sponsor, but there are still some great teams around if you want some test riders.
