I sell them now. The 06 is identical to the 05 in terms of frame , fork, and wheels. The stem and saddle are different than last year but comperable in quality. The tires are better this year as they use continentals rather than WTB caminos.
The "biggest" difference is the use of a power-splined truvativ turo crank rather than a conventional square taper sugino or ISIS spline like in previous years.
Oh, and the chainring is steel...and heavy.
Nothing to get excited about. Save some cash and buy a used or closeout o5 instead.
