While training on ERG Mode, Rizer's behaviour changes depending on the home trainer (Elite or other brands) and the firmware version you're using.
However, during these specific training sessions, as there's no direct correlation between tilt and power, we suggest always using Rizer Manual Mode in order to manage bicycle tilt during workouts. Using the Rizer in Power mode (ERG Mode).
Below please find the two possible options:
- COMPATIBLE ELITE HOME TRAINERS WITH NON-UPDATED FIRMWARE / THIRD-PARTY COMPATIBLE HOME TRAINERS
When using compatible ELITE home trainers (Direto XR, Direto XR-T, Suito, Suito T and Tuo) with NONupdated firmware, or Rizer-compatible third-party home trainers, the system automatically adjusts gradient based on the instant speed and power data sent by the interactive home trainer.
Rizer calculates gradient based on these workout data as if it was in Simulation Mode.
Below please find a practical example as to how Rizer calculates gradient if you're on a segment in ERG Mode with constant power set a 200W where speed varies for a cyclist weighing about 70kg:
|
Speed [km/h] – column 1 |
Power [W] – column 2 | Calculated gradient – column 3 |
| 10 | 200 | about 8,5% |
| 20 | 200 | about 3,2% |
| 30 | 200 | about 0,4% |
The value indicated by the simulated gradient (column 3) is the result of a calculation that considers speed (column 1) and power (column 2) data and determines their correspondent gradient value. Therefore if one of the two changes (for instance, we adjust speed) the calculated gradient adjusts automatically.
However, by using this function, due to the time it takes to elaborate data sent to Rizer by the Home Trainer and the usual continuous speed variations while working out, you might notice slight oscillations to the proper gradient.
As a consequence we suggest maintaining your speed as constant as possible because Rizer calculates a new gradient at every speed variation and will consequently position on a said gradient; therefore, the fewer speed variations, the fewer gradient variations.
Moreover, as stated above, it's challenging to maintain constant speed during these types of workouts, so we suggest using Rizer Manual Mode if the feeling that gradient oscillations convey is unpleasant.
- COMPATIBLE ELITE HOME TRAINERS WITH UPDATED FIRMWARE
When using the Direto XR, Direto XR-T, Suito, Suito T and Tuo ELITE home trainers with updated firmware and in Power mode, the Rizer stands still.
In this case, we suggest activating Manual mode in order to position Rizer at the tilt level you intend to maintain and/or move it when working out on your preferred gradient.
Compatible Elite models (Direto XR, Direto XR-T, Suito, Suito T and Tuo) and related firmware version
Updating the firmware of the compatible Elite home trainers to the latest version makes for increased efficiency of the Rizer-Home Trainer system.
Together with the Rizer market launch, some firmware updates have been released for the aforementioned Elite home trainers in order to streamline their operations when using Rizer.
For anyone using one of these models we suggest checking the firmware version of your home trainer via the Upgrado app and possibly updates it to the latest firmware version as it gets you:
- Increased Rizer response time for the training software.
- Stable and accurate tilt depending on the training software gradient.
- As there's no direct correlation between power and gradient, the system automatically remains still in ERG mode. It is however possible to use Manual Mode to adjust gradient at will.
