I rode a Soloist SL with Dura Ace 7900 on the weekend. Real strange not seeing the gear cables out front extending from the "brifters" (I only wrote this so I could use it Deej). Quieter than my Soloist (I need to find the source of noise on my bike). The 7900 brakes have lots of feel and power (and that was on carbon rims). The gear changes quiet and precise. Really nice. Looks great (especially on the Soloist).
And they still have the nerve to have it advertised on their homepage! Unbelievable
