1990 Tom Ritchey weld, Tange Logic chromoly tubing.
P (project)-23 series prototype, 21 pounds. 16 inch seattube, 20 inch toptube.
140mm rear tandem axle.

I say it a prototype as the production P-23 has the toptube cable guides more toward the seat\ headtube.
The team bikes were made of a lighter Logic Prestige tubing.
The P-23 Ritchey was the NORBA 1991-1993 winner. This is one of the first ones.
Under 050 in #sequence and the only Ritcheys without letter designation are early P-23 bikes, so this must be one.

Shimano shifter, Deore DX rear der.
ODI Ruffian hex off grips.
Sunour hex release axles.
SDG Bel-Air saddle.
