This frame utilizes Specialized’s advanced FACT IS (Integrated Structure) construction method. By separating the frame into four main parts — the front triangle, seat tube/bottom bracket, chainstays and seatstays — Specialized is able to optimize each carbon piece for its specific purpose and create a structure that’s incredibly light, impeccably stiff and impressively strong.
Tapered steerers and head tubes maximize front-end stiffness for awesome steering precision and control. The size bearings used in your headset will depend on the size of your Specialized S-Works Tarmac. Contact us for further details and information.
