This is Kappa K26Z a 26" retro tribute frameset to a CW Phaze frame, and a matching K16 pitbike. It is clearly distinguishable from an 80's original in several ways; most noticeably, they never made a 26" or a 16 in a Z frame. They both also feature updates for 1 1/8" threadless headtube, canti brake mounts and euro bottom brackets. They also feature several Kappa signature tooling items like the seatpost brace, machined headtube, and of course Hutch influences; not to mention solid construction. Kappa is not currently in business, we wish Scot well!
