Awesome. Aero dynamic TT bike. I fall in love with this bike at the first look.I replaced with Carbon fork & Zipp Vuka handle bar.I put on the carbon wrap for the body.The seatpost is original Zipp carbon seatpost. Fitted with Shimano Dura Ace components.   Zipp 2001 Story The frame that was to become the 2001 was first shown in prototype form in 1990, finalized in 1991, and entered production in 1992. The Zipp 3001 (which was a 2001 with additional boron strips stiffening the carbon fiber) was offered in 1997. 1998, the UCI announced that all non-double diamond frames would be illegal for road racing starting in January 2000. This led Zipp to discontinue production at the end of 1997.Successes of Zipp 2001While it was in production, it was widely regarded one of, if not the fastest bicycle frame in production. "Project 96", an attempt to create a US-only superbike for the '96 Olympics, fell into disarray when the data suggested that rather than building a new prototype then in tests, they should instead simply use Zipps rebadged as "US bicycles". Interestingly, despite 7 years of development after Zipps were shut down, it still seems that there are few or no frames as fast as a Zipp. The production frame currently thought to be the fastest, the new Cervelo P4, is, by Cervelo's own admission, slower than a Lotus, while it was known in the 90s that Zipps were as fast or faster than Lotuses.
