What is calibration?

  • With a smart trainer, the power accuracy lies in its calibration. This calibration process is especially important with smart trainers that have a tire-to-roller interface, also known as a wheel-on trainer. A wheel-on smart trainer is an affordable alternative to a direct drive trainer.  However, there are special steps that are needed to ensure that they are accurate and consistent. Slight variations in tire pressure, or in tension applied to the wheel, can increase or decrease the power reported to the app.  To ensure that your power is always measured consistently and accurately, you will need to check your tire pressure and perform the spin-down calibration prior to every ride. The spin-down calibration needs to be completed in the trainer's native app. Be sure that your trainer is properly warmed up, as tire pressure will change once the tire is properly warmed.  Be sure that your spindown time or numbers are within the trainer's acceptable limits (check your user manual), and that they are consistently the same.  Variations in spin-down time, even within the allowable limits may affect the degree of accuracy for your trainer. We recommend the use of a trainer-specific tire to prevent slipping and tire wear. Please keep in mind that the trainer response time on a wheel-on smart trainer may be longer than a direct drive trainer.  It is considered normal to have a 5-10 second lag time between the start of an interval and the time it takes your trainer to reach the target power.  We recommend keeping your cadence steady and smooth until the trainer reaches the target power and then smoothly and gradually adjusting your cadence to the cadence target. 
  • Since each bike setup is different, each bike needs to be calibrated with a smart wheel-on trainer to ensure the best possible accuracy. This is because no two bike setups are the same, as each uses different tires, rims, and recommended tire pressures, all of which play a role in dictating the rolling resistance measured by the trainer.
  • It’s this varied rolling resistance that the roll-down calibration is measuring and accounting for when calculating power readings or wattage. Since rolling resistance can change from session to session, or even within the same ride, we recommend performing a calibration as frequently as possible to keep your power numbers as accurate as possible.
  • You may notice that this recommended calibration protocol is for wheel-on smart trainers only. This is because direct-drive smart trainers do not need to be calibrated as often as wheel-on trainers, as there is no tire-to-roller interface. The direct-drive design reduces the variability in rolling resistance from ride to ride. While you can still calibrate direct drive trainers as often as you would like, often a weekly or even monthly calibration is sufficient.

 


Why should I Calibrate?

  • One of the best features of a smart trainer is its ability to provide power numbers. And when it comes to power, nothing is more important than accuracy.
  • We are “Bringing the outdoors inside,” meaning that we are duplicating the reality as closely as we can. In order to get the most accurate data possible from the app, you should calibrate before every training session- every time you mount a bike to the trainer, every time you pump the tire, every time you will feel there is something weird going on with the trainer, or at least once a week.
