Product Description
The Zipp 300 crankset is further improved upon for 2006 with the addition of the 185 Titanium BB. The combination of the two components with Zipp's proprietary 6AI/4V hardware result in a Crank/BB system that is more than 100 grams lighter than competing crank/BB systems. The heart of the Zipp 300 crankset is a revolutionary bonding process which allows the carbon fiber to bond to the aluminum with a strength similar to that which it bonds to itself. This process is so specialized and sensitive that it is thus far available only in the US, and only from 3 aerospace suppliers. While certainly not inexpensive, this process does increase bond strength by more than 3X when compared to traditionally employed methods, meaning that the Zipp crank can utilize two intricately forged and machined aluminum lugs only where they are needed and does not require a heavy internal aluminum spine to hold the crank together. This bonding process allows the Zipp 300 to use more than 200 grams less aluminum than other designs, allowing designers to utilize nearly 80 grams of additional carbon fiber in order to increase strength and stiffness resulting in a crank that is truly supreme in terms of stiffness and durability. Searching for an alloy that is as strong as 7074, but with significantly higher fatigue properties, Zipp discovered 2XXX aluminum from Alcoa. This aluminum was developed as a replacement for 2024 in military aircraft, and allows for the further removal of weight do to its significantly higher fatigue strength. In fact, Zipp 300 cranksets have achieved more than 3.5 million cycles at 1500N (300 lbs) without a crack initiation or failure in the bondline.
