Cervelo Project California The Ultralight Frame
Out of the new Cervelo’s test facility situated in the West Coast came out the latest product, an ultralight carbon road frame. This is the result of Project California. The Carbon Road frame was said to be weight at 700g and has a size of 54 centimeters. This same prototype was used by Test Team rider Thor Hushovd, however it weighed only 648g. This data was gathered from the Cervelo’s website where a video posted indicated the slight difference of 52 grams.
Pictures presented of the video illustrate a kind of “ Super R3 “ when it came to the basic layout and shape. The chainstays appear to be tall and wide and the seatstays are spindly , thus making the down tube presents itself in rather innovative “squoval” profile. Cervelo co-founder, Gerrard Vroomen remains mum regarding the matter and could not be reached for further comments and data on this matter.
Project California frame as seen by its flat black appearance indicates that it has carbon fiber dropouts rather than the bottom bracket and R3 – SL’s aluminum ones combined. For the purpose of eradicating the need for an alloy sleeve, a direct drop-in bearings or press fit cups are set replacing the standard BB 30.
However, it has not indicated that a taper head tube is included to add more grit and stiffness allowing the use of a bigger down tube which will lead to a heavier frame. It is very much likely that an external cable routing is set into place along with the usual round telescoping seatpost as conventionally seen. The video as posted by Hushvod has depicted that the ultralight carbon frame is closely similar to the S2 and S3 when it comes to the level of comfort it provides. The great difference is that the current models have a greater front triangle and bottom bracket stiffness.
Aside from being ultralight, stiff and considerately comfortable, Project California is also quite costly and will be made available sometime in August 2010 with a tag price of US $9,600 per frame. It will be releasing its limited “Made in USA” edition in the market where each frame is handmade by the engineers who designed it.
