Beautiful, elegantly crafted and artfully detailed - this pristine condition Serotta Ottrott frames in a 57cm size with Chris King headset is ready for your custom build project!Review of the Ottrott from big shark.com:The Ottrott is Serotta's finest bike, and quite possible--if you believe all the reviews--the finest bike ever made. No, it's not for everyone. But, then again, if you wanted a merely ubiquitous bike, no Serotta would be for you.The idea behind the Ottrott was simple: Combine titanium and carbon fiber in such a way to maximize their inherent strengths, thereby creating the ultimate ride. Sounds easy right? In actual fact, the process of selecting the materials and developing the construction methods to build the Ottrott took the better part of 6 years. The resulting Ottrott is a true cyclist’s bicycle: Serotta designed it to achieve distinct rider advantages. In short, the Ottrott is not only a bicycle thoughtfully designed to make you ride faster, but it is also is a bicycle that makes you want to ride; it brings your cycling experience to its highest plateau. Smooth, vibration-free and communicative road feel is just the beginning. The Ottrott also accelerates like a rocket and handles like it's on rails. It will take anything you can throw at it and then it asks for more – the Ottrott is the ultimate hedonistic pleasure for cyclists.To maximize rider benefits Serotta use the most advanced materials available. Perhaps even more important is that they use these materials in the right places: Carbon fiber for stiffness and vibration damping; titanium for a snappy ride quality and durability. The Ottrott’s Colorado Concept main tubes are now made from their groundbreaking Torsion Core carbon fiber. This new technology means the Ottrott’s drivetrain is as stiff or stiffer than before, while the tubes themselves are an average of 16% lighter. The new Ottrott gets more than just new carbon fiber. The new bottom brackets and head tubes are radically machined in the CNC shop to reduce excess material. This painstaking process shaves grams from these parts without compromising strength. The butted S-Bend chain stays are functional works of art that stiffen the drivetrain and provide a snappy ride quality. The available ST stay and pivot system keeps the rear tire glued to the ground for greater control and maximum energy transfer.All this technology isn’t for nothing. It is specifically designed and utilized to create the perfect ride – the Ottrott. $5300 Ottrott ST frame with carbon stays, $4900 Ottrott frame with titanium stays"
