Upgrades from Soloist Carbon

Lighter frame - While the Soloist Carbon is among the lightest frames in the ProTour (as determined by independent sources like the French magazine Le Cycle), the SLC-SL shaves another 200g off the weight to become one of the lightest frames in the world (real weight, not claimed weight) and the only in that select group with such aerodynamic features.

Higher bottom bracket and torsional stiffness - The Soloist Carbon is Jens Voigts favorite bike in 2006. So maybe there was no need to increase the bottom bracket and torsional stiffness of the SLC-SL beyond that level, but nonetheless we have raised it another 5-10% for optimum handling and safety.

Features

Outstanding aerodynamics – Like the Soloist Carbon, the SLC-SL uses the best airfoil shapes designed for bicycle speeds. Cervélo doesn’t use standard NACA (now NASA) airfoil shapes, as they are mostly designed for speeds much higher than are attained on a bike.

Light, but efficient – It is easy to make a light frame, just use less material. But the SLC-SL is light by using material in the right places, rendering stiffness properties in the BB and in torsion that are even 5-10% higher than the already leading-edge Soloist Carbon.

New profile downtube - Our work into improving the downtube and headtube on the P3C has directly benefited the SLC-SL.

Horizontal teardrop-shaped sloping toptube - Since the toptube has a slope to it, the aerodynamics can be improved by giving it the proper airfoil cross section in the direction of the airflow.

Stealth aero headtube – The headtube is ultra thin and only 1mm wider than the P3C headtube. Although the leading edge is kept straight, the sides neck down in the center section, resulting in a very good airfoil shape around the headtube in combination with a classic side profile.

Oversized bottom bracket area – The increased volume of the bottom bracket area provides even greater BB stiffness. The smooth contours of the BB volume help both for this BB stiffness and also for its strength as the fibers have a much more continuous path to transfer the loads better.

Wolf seatstays – The seatstays have an asymmetric design from our Wolf family of airfoil shapes, designed for optimal airflow around a thin frame member interacting with a spinning wheel.

ICS Internal Cable Stops - The best internal cable stop system available. Easy to install, easy to service, easy to keep clean and improved aerodynamics.
