In order to avoid this, remove the sensor form the crank. SLOPE The maximum simulatable slope on the RealAxiom is a function of speed and the weight of the individual rider. In fact, the power required to pedal up a slope is function of the speed (faster = more power] and of the weight (the heavier the rider, the more power is required to climb any given slope]. Each rider has a maximum slope given his weight [i.e., for a 60kg (130lbs] cyclist at 24Km/h (15mph) the maximum simulatable slope is
