However they said they still producing the bar but unable to sell them and were unable to tell me why. I'd say a few companies have used this bar and had them rebranded.
I now own a set of perko bars 34cm c-c. And I can confirm that they are awesome. I used to have a set of alpinas for reference.
the BT sprint bars are made by BT, they only come in 36cm and although they look similar the top aero part of the bar has a slight curve to it.
edit:
this is the link to the Trigons bars, the picture is of the larger version but they have measurements and diagrams of the different sizes.
