Not all of us are mountain goats. Anything that purports to make that slog up Guardsman Pass a bit easier is sought out with enthusiasm. Boardman knows the importance of weight when it comes to climbing, as it proves in the new SLS frame. The SLS was designed to ride over the highest mountain passes without an extra ounce of weight. The SLS 9. 8 build is so light in fact that it comes in at under UCI weight class limits. The SLS 9. 0 Complete Bike is the introductory package of the SLS frame, so that anyone is able to reap the benefits of a lightweight bike. And it's no less impressive. The SLS frame is high modulus carbon fiber monocoque construction. The definition of the monocoque process is hidden within the name -- 'mono' being Latin for 'one,' and 'coque' being French for 'shell.' So, as logic would have it, monocoque carbon fiber is formed as one piece in a single mold. This process allows virtually any tubing shape to be created. To develop a frame profile that maximizes strength, stiffness, and weight, the SLS was designed using Finite Element Anaylsis. FEA is a process by where specific loads applied by the rider to the frame are simulated but with far greater force. This helps to identify how the stresses and loads are distributed across each component. Using this information, material is placed where it is needed and removed where it isn't. For example, the down tube has been shaped to specifically address strength, stiffness, and weight. The one-piece monocoque design incorporates a one-piece carbon PF30 bottom bracket and optimized, oversized chainstays. This design transfers power from the crankset through to the rear drivetrain and wheel so that none of your watts are wasted. Additionally, the profile of the seat stays increases shock absorption and reduces the weight of the frame. The complete frame and fork weigh in at approximately 850 grams. The SLS Endurance Racing geometry features stability, predictable handling, and comfort for ...
