Calibrate zwift

Most smart trainers have their own spin-down calibration protocol which can normally be accessed and carried out using an accompanying app.

Last week Zwift began rolling out updated firmware to Zwift Hub owners. The big feature of the latest firmware version 4. Essentially, auto calibration is the same as a manual spindown calibration… it just happens automatically every time you coast. So whenever you supertuck down a hill, or hop off your bike to hit the loo between your warmup and race, the Zwift Hub will calibrate itself, optimizing power readings automagically. One Zwift Hub advantage is its direct integration with the Companion app. It just works.

Share on:. Wahoo KICKR series of smart trainers all require to be calibrated for power accuracy when riding indoors. Wahoo has developed an app to perform this calibration on their device. Then, is it better to perform the calibration in Zwift or in Wahoo app? Stop wasting time deciding where to ride in Zwift with my Zwift route guide. Quickly choose a route based on distance and average gradient. So overall both options should work, but there are lots of people having issues with calibration and generally, it gets solved using the Wahoo Fitness app. A spindown test consists in measuring the deceleration of the trainer after reaching a target speed to measure the friction. If the wheel was not exposed to friction, it would turn indefinitely. But we all know that friction affects the wheel rotation. The more friction, the faster it decelerates.

You get to see the temperature results and you can keep track of this information to see how it calibrate zwift with time. Thanks for your recommendation. Login to your British Cycling account.

So then I tried to pedal to a normal calibration speed. The speed is being read and the app even tells me to stop pedaling but the calibration never succeeds. Looking into this now for you. Does it work when you are doing the workouts? Thanks for looking into this, IvyAudrain!

Most Zwifters realize that smart trainers are complex, expensive electronic devices which require calibration and properly-functioning firmware in order to operate properly. Yet many riders have never calibrated their smart trainer or checked for updated firmware! For all but a few smart trainers including the Tacx Neo line, the new Wahoo KICKR 5 , and most smartbikes calibration is necessary to ensure power readings are accurate. Firmware is the code which tells the trainer how to operate — updates typically result in increased power accuracy, more stable operation, and a better overall ride experience. We thought it would be helpful to publish it as a standalone resource, so here it is! The 4iiii app called "4iiii Device Configuration" on Android lets you update firmware and calibrate your 4iiii devices. It also lets you change some settings on your Fliiiight smart trainer, which may be necessary depending on wheel size. Although reviews are less than stellar, the Toolkit app from Bkool is supposed to enable owners to update the firmware on their Bkool trainers.

Though some 3rd party apps like Zwift can perform spindowns, Wahoo always recommends using the Wahoo Fitness app for best results. Wahoo says:. A factory spindown is used to determine brake strength, and is only required if a significant error exists in power after performing a regular spindown. Wahoo has hidden the advanced spindown utility in its mobile app, presumably to avoid users accidentally running it too often.

Just one follow-up question: when you talk about calibration data being stored on the device, are you talking about the head unit or the smart trainer?

Temperature is the probably the biggest variable that needs accounting for and, in the same way you warm-up, so too does your trainer. Remember me. The calibration is internal to the trainer so if you calibrate it on the Tacx Utility app, it will carry over to TrainerRoad. So whenever you supertuck down a hill, or hop off your bike to hit the loo between your warmup and race, the Zwift Hub will calibrate itself, optimizing power readings automagically.

Smart trainers and power meters are improving in terms of accuracy and reliability as the technology matures, and I think the vast majority of Zwifters enjoy acceptably accurate power numbers today. Additionally, other riders may be using uncalibrated trainers or trainers with known accuracy issues. The only way to test the accuracy of your power numbers precisely is to compare them with a power meter you know is completely accurate.
