Hollowgram and SAVE technologies

The evolution of the revolution. 13 years ago, the original Cannondale HollowGram crank started the BB30 revolution and set a new standard for ultra-light, super-stiff cranks.  These hollow cranks are created by bonding together two machined, heat-treated clamshell halves with a super-strong anaerobic bonding agent. Extensive FEA modeling and physical testing have allowed Cannondale to refine the internal and external shapes for the ultimate in stiffness-to-weight. The results is a crank light and stiff enough for the top road race machines but still so tough, it is used  on their mountain bikes as well.

SAVE is not strictly a technology per se, but more of a manufacturing approach – by manipulating the composition and material of their frames and components in certain areas, Cannondale claim that SAVE can enhance frame compliance (comfort) without sacrificing rigidity and performance.This Cannondale model has SAVE technology in the Seat Post, Seat Tube and bars. SAVE seat tubes have a sloping design that is designed to help smooth rides in concert with Cannondale’s smaller diameter SAVE seatposts.
