Kestrel is not a Bikesdirect brand like Dawes or Motobecane.
Kestrel is sold through bikes shops, as well. For that matter, I see Bikesdirect has Schwinn on their list. Schwinn is not a BD brand.
Kestrel Bicycles | The First Name in Carbon Fiber and from there you can look up dealers in your area.
I really have no clue who
makes them these days. But they have a $6100 bike on their website...Ultegra Di2 for $4,500.
FWIW...they are owned by ASI (Advanced Sports International) and as has been mentioned they (ASI) also own Fuji.
