No athlete will ride their fastest, even on the finest lightweight, aerodynamic frame if it isn’t optimally fit. Each athlete needs a different fit based on a variety of factors. Attempting to develop more aerodynamic positions, many athletes create biomechanical inefficiencies. It won’t help to find a position that is 10 watts more aerodynamic if you lose 20 watts due to biomechanical inefficiency.
Fitness Concepts offers aero bike fittings. Our aero fit specialist, Ken Mierke, will determine your optimal bike fit based on the duration and terrain of your key races, your pedaling style, skeletal structure, flexibility, and strength ratio of hip-extensors to knee-extensors.
Perhaps the most critical aspect of aero bike fits is handlebar height. Along with fore-aft position, this determines a rider’s torso-femur angle. Getting this angle right is the key to balancing aerodynamics with efficient power production. Fitness Concepts aero bike fits include ventilation tests at a set wattage, gradually lowering the handlebar. At some point, as the handlebar goes down (and aerodynamics improve), biomechanical efficiency will be lost. When this happens, a rider’s ventilation at a given wattage will increase significantly. By testing this, we set handlebar height just above the point of dramatic ventilation increases.
