Stradalli Phantom II Full Carbon Time Trial Bike. Shimano Ultegra 6800 11 Speed. Stradalli 50-85mm Aero Carbon Clincher Wheelset 100% Carbon Fiber The Phantom II, the most aerodynamic TT frame we have ever produced. Starting with the front end, we made some dramatic changes to the previous model. To reduce parasitic drag, we designed a bayonet style fork that cuts through the air like a knife and relocated the TRP front brake to the back side of the fork. We then integrated the fork, stem, and handlebar to create an aerodynamic position for the rider that will give them an unfair advantage, but still offer spacers to bring the pads up for added comfort. The newly designed front end offers one of the lowest amount of frontal surface area out there.The tube profiles are dramatically thinner than those on the previous model. They offer implausible aerodynamics, and the seat tube provides great shelter for the rear wheel. To reduce even more drag, we moved the TRP rear brake so that it is now nicely tucked in underneath the oversized chainstays. By moving them to the chainstays, we were able to increase the aerodynamics of the frame. The Phantom II is built around a BB30 which offers implausible stiffness out of the crank. This bike is designed that can assist you shave valuable time off of every race. The Phantom II is likely one of the most aero frames available with hidden, integrated, brakes. -BB30 Bottom Bracket ready -Internal Cable Routing. BB30:There is numerous buzz about the “new” BB30 standard, but the very first thing to clarify is that the design is anything but new. We will trace the BB30 origins back to 1993, but its benefits today are more relevant than ever: BB30 provides a significant increase in torsional stiffness (pedaling efficiency) even as reducing weight and maintenance needs (easier to service – longer lasting bearings). BB30 is a tried and true system offering peculiar power transfer efficiency in a simplified design.This BB30 frame also accepts an adapter sleeve that allows the frame to be used with any standard crank that utilizes a threaded bottom bracket. (Adapter sold One at a time). This adapter is needed for use with Campagnolo and Shimano cranks.
