The Kilo TT definitely has a track geometry. The current Langster Comp and S-Works are also track geometry. The regular Langsters (including the "City" editions) are roadie geometry. The older Langsters (pre-2007) were all track geometry as well. The way to tell is by looking at the HT and ST angles, HT length, and the BB drop. Steeper angles + short HT + higher BB height usually = track geometry.
