Pretty impressive. TK2, Mavic Ellipses and all!

Yeah, I don't mind riding a Langster on a fire road so much as I hate the flats I tend to get when it hits one of those odd shaped rocks at the wrong angle.

Still, riding fireroads is expressly prohibited with my track bike. Bummer!
(not to mention that it (like a newer TK3 or T1) is a lot stiffer than the bikes photographed above)
