Chris Boardman, star British cyclist and multi-time world champion and record holder, believes that the cyclocross bike is the most versatile bike out there. From racing, to touring, to commuting, Boardman's CX frames are designed with all the necessary details to make each discipline a delight. In fact, Boardman believes in the 'cross bike so much that they have developed and engineered three separate frames for every level of rider. The CXR 9. 8 is its new flagship, top-of-the-line model. And although 'cross is one of the few discipline that Boardman did not race, you can be assured that the frame received the same attention to detail as his time trial bikes. The CXR was developed using the SLR frame as its inspiration. Every tube was meticulously examined and tested to be the most efficient and lightweight as possible. Using the latest Finite Element Analysis (FEA), Boardman was able to test many different combinations of fiber types, fiber directions, resins, and tube shapes to ultimately come up with the CXR frame design. With the main load path in any bicycle running from the head tube, down the down tube, and then through the bottom bracket and drive-side chainstay, Boardman zeroed in on these critical areas to add material where it's needed and remove it where it's not. The oversized nature of the down tube keeps the steering sharp, with the oversized bottom bracket handling pedaling forces. The material selected for the CXR's frame is an ultralight, high modulus unidirectional carbon fiber, constructed with a full monocoque design. Similarly, the fork was built out of the same predictable, race-tested, and ultralight carbon fiber. The SLR's mold incorporates a one-piece PF30 bottom bracket and oversized asymmetric chainstays, which assist in both power transfer to the drivetrain as well as increased braking capabilities. The seat stays were given a wishbone profile which assists in a smooth ride. Along these lines, the full carbon fork was built ...
