Power Measurement: Gears |
How do you use your gears? What gear were you in for the sprint? Is your cadence uniform over a range of gears? In the plots below, the vertical bands are the data points at the same gear development. Gear development, the distance a bike moves forward with one revolution of the pedals, is calculated from Cadence and Speed. We see bands of data because the Cadence values are not precise. These bands may not always show up in your data. This depends on how a rider pedals and how the power measuring device measures cadence. The time increment between data points must also be around a second or less, otherwise the data values for cadence are an average, not an instantaneous value. This could be useful for determining the gear used for a particular power measurement made while riding a fixed-gear bike. Would we expect to see the highest torques in the lowest gears?  Gear Development verses Torque.  Gear Development verses Power in watts.  Gear Development verses Cadence.  Gear Development verses Hear Rate.  Gear Development verses Speed.  Gear Development verses Power for a short Time Trial.  Gear Development verses Cadence for a short Time Trial.
