It’s worth bearing in mind before you embark on this review that the Cervélo S5 is now three years old, and in bike development terms that means it’s probably due an update this year or the next. Why bother reviewing what might soon be an outdated model? Well, according to our own wind tunnel testing the Cervélo S5 is still absolutely one of the best aero bikes on the market. The fastest, at zero yaw, even compared against far newer bikes like the Specialized S-Works Tarmac SL8 and the Factor Ostro VAM.
It is also still being used at the highest level of the sport, and when a new model eventually replaces it, the older model will then likely go on sale, and might become a more attractive proposition for a would-be customer.
