Welcome to Au.S.F.R.

 We love bikes. We love all kinds of bikes - sports, cruisers, cafe racers, you name it we can find something to like about it!

We set out over a decade ago to bring to you only the highest quality of parts. We are unashamedly elitist and firmly believe that if you want a quick fix of cheap gear you can get that kind of hit from your local discount bike barn.
So pull up a chair, put your feet up and bask in the glory of some of the Worlds best billet bits.
See you in the twisties.
