This Cervélo S5 road bike features a build configuration quite common in China: the original Shimano Dura-Ace hollow aluminum crankset has been replaced with a carbon fiber crankset paired with a spider-based power meter—a setup that ensures accurate power measurement while reducing the overall system weight.

(As an aside, I had hoped that the aerodynamic advantages of this bike would help me hit an average speed of 40 km/h for the first time. Unfortunately, that didn’t happen—my first ride resulted in an average speed of 38.9 km/h with an average power output of 315 watts. It looks like I still have some work to do!)
