Time for a new bike. Currently riding a Kona Unit. Thought I wanted a Vassago Verhauen. Then I rode a friends Kona Raijin and loved it (handling and the lightness of the Ti). I have never ridden a Vassago Verhauen or Optimus (same geometry) and there is no where in my area to try one out. Can anyone speak to the difference in handling characteristics between a Raijin or the Optimus Ti?
