just looked in the archive section, the kilauea had project twos and the cinder cone had rock shox.i had rock shox when i bought the bike, but wanted project twos so went for the suspension adjusted ones.the chain stays are both level.
The Cinder Cone was also sold with the same triple-butted 41cm P2s as were standard on the Kilauea. The geometry of the two frames was identical.
The choice of the 41cm length for the P2 was on the basis that the 50-63mm travel forks that were then available had an axle-crown length of 42-43cm, which means 41cm or so once loaded with a rider on board. So the frames were built to give the desired 71 degree head angle with a 41cm P2.
With a 44cm P2, the head angle falls to 69 degrees. This makes for a steadier, slower style of handling, less inclined to turn corners. Some people prefer that, but I'm just saying that it doesn't give you the handling quality that the bike was designed to give you.
