Uphill Climb

21 days. 2,000 miles. 16,000 feet of elevation. And every ounce feels like a ton.

Breaking Through

Every July since 1903, the Tour de France puts cyclists (and their bikes) to the ultimate test. Since 1995, Cervélo Cycles has met that test with technological innovation that has reinvented the sport.

Col Agnel is an Alpine pass on the French-Italian border. At over 9,000 feet of elevation, it’s one of the highest roads in Europe and one of the most challenging climbs ever to be part of the Tour de France.

Give & Take

In cycling design, an improvement in one property usually comes at the expense of another. To make a frame lighter usually requires sacrificing stiffness, which can lead to wasted energy during a climb.

The fight to stay on the cutting edge of bike engineering is nearly as cutthroat as the Tour de France itself. Cervélo, to stay ahead of the competition, needed to find a material that would avoid this performance seesaw.

Nano-engineering

The 3M Advanced Composites team had begun experimenting with matrix resins in groundbreaking ways. By manipulating particles the size of a molecule (6 millionths of an inch), the scientists were able to make materials that could do things never imagined.

Only 3M could manufacture silica particles this small and regularly shaped. Resins with this type of nanoparticle are able to completely surround carbon fibers, resulting in materials that are both stiffer and lighter at the same time.

Rca

Cervélo Rca: the lightest bike frame strong enough for the 2013 Tour de France.

A Perfect Fit

The breakthrough happened when 3M approached Cervélo with the new material. Cervélo, a thought leader in engineering, was the perfect cycling company to make the most of the matrix resins.

Light Is Might

At an average weight of 667 grams, the Rca frame is so light, attaching a water bottle would double its weight. But the 3M resin’s ability to also provide strength was what Cervélo was looking for. Rca riders now have an edge in performance that will more accurately reflect the power they put into their races.
