BIKE FIT PHASE TWO: Dynamic Delta Power Analysis

  • With a preliminary geometry chart in hand, we then move on to phase two: dynamic power testing. This entails the use of a hand tooled laser jig, which allows us to transpose the two dimensional initial geometry parameters into three dimensions quickly and accurately. Specifically, we use the laser jig to duplicate the initial geometry chart on a custom crafted, fully adjustable test bike. Then the rider works out on the stationary test bike, which is also equipped with wattage metering capability.

    With your initial position as a reference, a baseline power output and comfort level is established. Fine adjustments to the test bike dimensions can yield dramatic gains in power and comfort. Based on this dynamic power testing analysis, our expert mechanics then assemble and customize the rider’s actual bicycle, in exact accordance with the results of their power test.

    We recommend that you ALWAYS start your bike selection process with the fitting, then choose a frame and component group based on the results of the first two phases of the FitLab process.

    This is a major point of departure from the approach used by most retailers. We recommend that you ALWAYS start your bike selection process with the fitting, then choose a frame and component group based on the results of the first two phases of the FitLab process. This ensures that you have sufficient information to select a frame which not only fits your body comfortably, but also that will be correctly proportioned to maximize the handling characteristics you are looking for. This difference is KEY! At 95% of the bike shops out there, you will be sold on a bike BRAND, or perceived bargain component package, or frame color- or whatever it is that you respond to initially. While it may be the path of least resistance for you and the retailer, it is exactly the OPPOSITE of how frame and component selection should occur. This semi-random selection of a bike frame rarely results in a perfectly fitting bike for the rider. We have served countless customers who suffered through weeks, months or even years of fit disaster damage control which never solves the underlying frame geometry problem. This is why we feel so strongly about selecting the bike frame to fit the customer perfectly, NOT forcing a fit of the customer to the most conveniently available bike frame!
