Koga have a new(?) bike out called the Senko. New to me, but possibly not new to you.
I find the chainstays and seatstays to be worryingly thin though. Other modern track bikes have thicker stays. I'm sure that a thicker stay makes for better power transmission, and less flex? However, I am well known to be bereft of a clue, so I stand to be corrected.
The senko was the 2010 replacement for the full track pro. This is the second year of senko's being available.
