The build may be suitable for riding in a vaccuum chamber or possibly on a track (less the 7-speed cluster). I found that anything under 17 starts to lose stability. I have a 17.2 titanium which is perfect , a 16.3 alloy-carbon which rides OK, a 15.6 (S-Works) which is "skiddish" at best, and my Colorado climbing bike (Calfee Tetra) at 14 lbs. 13 oz. which is AWESOME for climbing miles into the atmosphere but an absolute B!&*CH to hold a line when descending. The thing gets so loose on switchbacks and crosswinds that it is almost unreasonable to ride. On flats against the wind, there is no momentum to carry the wheels forward. Heck, flats WITH the wind is almost too much of an effort to keep the cranks turning.

The pic with the scale is without pedals (13 lbs. 15 oz.).
