Frame size is M. The bike is 2 years old and only ever bin ridden is sunshine. Beautiful bike and extremely quick with smooth gear changes and integrated power meter. The Bike is fully carbon including the wheels that are SLR 1 carbon aero wheels. Meticulously developed for best-in-class aero road performance, this razor-sharp road racer was born to sprint, chase or make your attack. The frame is handcrafted using Advanced-grade composite material to produce a bike that’s lightweight and stiff with a responsive ride quality. The components are as integrated as they can possibly be, with smooth lines from the handlebar and stem, internal cable routing, and a WheelSystem that uses a 65mm deep rear rim for maximum aero performance and a shallower 42mm front for added control. Even the disc brakes are integrated into the frame, with flat-mount calipers and thru-axles designed to optimize the technology.
