If you are looking for the absolute lightest bike without sacrificing stiffness or strength, you can't do any better than the R3. As a benefit, the R3 will also fit wide tires, even narrow cyclocross tires, for those interested in riding through mud or harsh winters. The R3 is strong and ideal for bad conditions, yet light and stiff in bottom bracket and torsion.

Available Models: R3

The S1 has the technical features, the ride quality, and the pedigree to be a very expensive "super frame", it is in fact the least expensive way to ride the exact same frame the top pros ride. If that isn't reason enough, it also morphs into a part-time TT/Tri bike for those who desire so, simply use the Cervélo aero seatpost with flippable head.
