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 Topstone Carbon 2 has SAVE technology in the Seat Post and Seat Tube. SAVE seat tubes have a sloping design that is designed to help smooth rides in concert with Cannondale’s smaller diameter SAVE seatposts.
