As alluded to in a previous post, the geometry for the Kona Rat frame:
(in both metric & imeprial measurements, save you dividing by 25.4)
Advertised size 540mm/21.3"
C-to-T seat tube 520mm/20.5"
Top tube length 550mm/21.7"
Seat tube angle 75*
Head tube angle 74*
Chainstay length 388mm/15.3"
Fork length 365mm/14.4"
Fork offset 37mm/1.5"
Bottom bracket height 281mm/11.1
Head tube length 130mm/5.1"
The below image shows the nice clearances, but as a package its not as "aggressive" as the numbers suggest. With a reasonably long top tube, toe-overlap won't be a major issue, yet the steep angles and short rear triangle will keep the over-the-pedals body position and quick handling.
Proof is in the pudding, so to speak - I'll do a full test report when its all put together.
