2010 Cervelo S2

The comfortable aero tubing frame

“The workhorse frame for Cervélo TestTeam” The S2 already has the reputation for being the ultimate pro bike; not surprising, given its long list of victories. But how about comfort? Truth be told, many frames with aero tubing lack in comfort. But at Cervélo, we have been designing aero bikes since our inception, so we have the most experience in building aero frames without sacrificing the traditional focal points of weight, stiffness, strength and comfort. This may explain why only the Cervélo TestTeam used aero frames at the early season cobblestone races (including Thor Hushovd's victory at the semi-Classic Omloop Het Nieuwsblad). While for some races the R-series may still be better, to know that the S2 (and the even more compliant S3) excel even on the cobblestones shows you can have all the usual characteristics of a great frame AND aerodynamics on top of it. That's great news pros and non-pros alike.

Upgrades from S1

Lighter frame - The S1 is very competitive in weight (as a past winner of Liège-Bastogne-Liège, it has to be), the use of carbon fiber allows a further weight reduction. This makes the S2 very competitive in weight even compared to frames without an aero advantage. Higher bottom bracket and torsional stiffness - While even the biggest pro riders have no complaints about the S1’s stiffness, the S2’s additional torsional stiffness make it track through switchbacks in fast descents even better.
