The tech you get
A lightweight 300 Series Alpha Aluminum frame with shaped tubes and Invisible Weld Technology for the looks and handling of a far more expensive carbon bike, a Shimano Tiagra groupset with 20 speeds, an Emonda carbon fork, powerful flat-mount hydraulic disc brakes, and internal cable routing in both the frame and fork.

The final word

Why you'll love it
