Speed meets sophistication: the 2018 Cervelo S5 eTap is engineered to ride and handle like a pure aero road race machine. It begins with a carbon layup that’s tuned to optimize stiffness laterally and torsionally while shaving every gram possible. Cervelo’s aero geniuses hit high gear with a dropped down tube and an extended seat tube cutout to smooth the transition of air from the front to rear wheel with nary a hiccup. The wind-cheating wizardry continues with brake-shielding seat stays and internal cable routing with top-tube entry. Cervelo’s mammoth BBright bottom bracket provides Herculean power transfer while their renowned geometry means it’s as comfortable as it is responsive and fast.
