Doug,
I can tell you some basic things about how Dave thought and designed frames. He basically made track bikes for the road, insofar as geometry goes. He also liked extra heavy and/or stiff tubing.
The S-22 was made from oversized custom designed True Temper tubes. The chainstays are about 6 feet in diameter. ;-) The S.T. and D.T. were conical with the larger diameter (1 3/8") at the BB shell. The forks were unicrown and the dropouts were plug on type designed for the large tube ends.
Dave made steep head angles realitive to the frame size and the fork rake was generally around 3.6cm or so. The seat angle will be "normal" for the size frame in question but the bb height is on the high side, around 10 1/2" to 10 3/4", depending on the bike. TT length will also be standard to slightly short for the frame size.
Hope that answers your questions. Not sure why it matters; if you find one your size it will bee what it is. It's a race bike from start to finish. The Mod. 100 and Mod. 101 were simularly designed around standard sized but heavy tubesets.

Howdy folks.
Do any of you know what kind of geometry was used on the S-22 model and how it was sized (evens, odds, every other cm, C-T etc.)? My understanding is that these were standard builds, not custom. I would like to know the angles and such in the 53-55cm size range.
Thanks,
