Cervelo Caledonia-5 Disc Ultegra Di2 11spd Zipp 303S - 2023

Faster handling isn’t necessarily better—we engineered the handling based on the specific use-case. In this case it’s Roubaix. Roubaix is harder on bikes than any other race on the calendar, and there’s zero margin for error. We increased the rear center (compare this to the R3 that was raced last year), lowered the BB, and increased the trail. The handling is still fast, but we’ve added stability.

We’ve stayed away from compliance gimmicks; no elastomers or funky tube intersections. Our proven library of tube shapes is at the core of every bike we design, and these tube shapes all have different known attributes.

You can’t cheat physics. Triangulation and the force required to deflect is at the heart of the ‘double-diamond’ frame design, and has been since the safety bicycle’s inception. We know how our tube shapes behave, and it’s a matter of placing them in a layout that achieves the desired compliance based on that deflection. The simplest solution is almost always the best.
