Yowza, we love our Infinity. It’s really white, sort of ethereal looking, such that the gorgeous Tiagra cranks, black wheels, tires and controls could be attached to a cloud. With your butt parked on the saddle and feet clipped in, this vaporous apparition proves to be more than just a visible collection of condensed droplets. From the first spin of the cranks to when you grab the brakes to put a halt to the motion, you’ll come to understand the term clear air turbulence.
