If you have been watching the Tour de France this past week, you may have caught the latest offering from the Cervélo factory. Designed in top secret over the past year, the super trick matt grey R5ca frameset is the lightest/stiffest carbon frame made. Created in Cervélo’s Project California facility in California, the R5ca has minimized every gram of carbon and has utilized the significant experience the company has collected over the last few years of international racing. Cervélo has always created bikes that are outside of traditional building ideas, this is their strength, and the R5ca is no exception. With details like a massive bottom bracket, a tapered steerer tube with two different sized bearings to minimize weight, a tapering top tube and scary-thin wishbone stays, and a 72-degree seat angle to eliminate a heavier seatpost, the R5ca continues Cervélo’s domination in bicycle design. The frame is 688 grams, has a 40% increase in stiffness and is 150% stronger than traditional frames. The projected retail price for the frame is $10,000 with only 300 frame sets being produced. If you are a cycling fan, do not panic, all this thinking will eventually make it to their production models.
