The Sonoma was one of the first "long travel" bikes which at the time meant 4".  The regular Sonoma came in natural aluminum and included the frame, stem, seat post, Aheadset, front derailleur trunion bolt and retailed for about $1,700.  For an additional $500, you could step up tot he Ultra model which had a powder coated front end and added a Ti bottom bracket.

 Both frames were available in 3 sizes (small, medium and large) and had the ability to adjust the seat tube by 15 degrees.   The forks and original rear shock both ran in the 30-40 psi range which made adjustments much easier.  Maximum rider weight was listed at 220 pounds.  It is kinda neat to see a company try to make a complete package instead of buying off the shelf parts to hand on their own frame.  The designers of the frame were J. Scott Strom and Tibor Fischl.
