Cervélo R5ca – California Road Bike
After two years of studying and crafting, Project California has finalized its new bike frames. Phil White and engineer Don Guichard were ready to show off their initial results after the Tour of California. The R5ca or California as it is called, is Cervélo’s latest creation, an ultra-light steed that weighs as little as 680 grams including the hardware.
The makers of this frame are planning to produce 300 of these this year making it sort of limited edition. With a tag price of $9,800 for this frame, it also comes with a fork, headset, zero-offset seatpost and a bundled Rotor crankset (they are not as bad they look). But the facility does not only aim on selling frames, they are also designing, testing and analyzing each product that they fabricate.
The frame is made of 350 different plies of carbon that took about 90 minutes just to cut. With a new bottom bracket standard dubbed as BBright, they took pieces from both BB90 and BB30, using a 30mm axle and all the space that the non-drive crank and chainrings will allow. As a result, the asymmetrical bottom bracket created the best of both worlds.
This means that the whole frame can be bigger since it was made asymmetric. All the tubes are bigger now. The down tubes are wider as well as the seat tube and the chainstay is double the size, making the bottom bracket 40% stiffer. Before making the “standard” for the R5ca, Rotor, FSA and Zipp have created compatible BBright cranks as well as adapters for SRAM, Campy and Shimano that will soon be available.
