there is this one on ebay too, seems like an ok BIN
BT track bike – Pista – single speed – Velocity Deep v aero – campagnolo | eBay
thou not in the same league as the one above
that looks like a repainted Fuji Track Pro to me.
BT used to make aluminum frames.
And 9000 for the everything excluding wheels is pretty overpriced IMO. It’s just a cyclone with cable routes.
and derailleur hangers and brake mounts…and the fact it’s one of not many.
but is still priced according to feelings.
this wouldnt sell for half the asking price, person is insane
not entirely true. they made a handful of prototypes.
brendan is one of them.
this is rach’s aluminium one, so nice.
Good reason to stop making them… 
dude, it’s BB, not BT.
