This rarely found and new, never ridden Basso Viper frameset was the top of the
line steel frame offering from Basso. While there are some more well-known
"name" frames like Colnago, Merckx, DeRosa, Tommasini, Gios, Pinarello, etc., I
have never seen a more consistent builder of quality framesets than Basso. Their
selection of high-end customized steel tubing, quality of the brazing and lug
work, durability and beauty of the paint jobs, and the smooth and stable ride of
the assembled bike all are signatures of the Basso brand.

This Basso measures 54cm from the center of the bottom bracket to the center of
the top tube (or 55cm from the center of the bottom bracket to the top of the
top tube, or 57cm from the center of the bottom bracket to the top of the
extended seat tube) with a 54.5cm top tube length. The seat tube angle is 74
degrees with a 73 degree head tube angle. The head tube measures 125mm and the
steerer tube is 185mm long. Rear spacing on the vertical rear dropouts is 130mm.

The Viper frame is painted a brilliant metallic racing yellow with blue decals
and comes with a matching yellow 1" unicrown threaded steel fork. There are
Basso engravings on the rear dropouts and the brake bridge.

The frame has two sets of water bottle bosses, a braze-on derailleur tab, and
the rear brake cable housing is routed at 7 o'clock on the top tube

The frame is a combination of a beautifully fillet brazed head tube and seat
tube/top tube junction with a lugged bottom bracket. The tubing is steel
proprietary Basso Concept Ultra Light tubing designed and manufactured
especially for Basso.

This frame and fork have never been built up and are in wonderful condition.
There are a few small paint chips from a decade of storage waiting for someone
to build this frame into a fast road bike, but they are only noticeable close-up
and do not detract at all from the beauty of this frameset. The bottom bracket
shell has been faced and it is ready to build up.

$300 picked up in McAlester. Pics available on request.

Thanks,

Frank
