- Sprint Detection is activated when a riders maximum average power of 10 seconds and 30 seconds is displayed.
- Sprint Detection data can be analyzed in the "Cyclo-Sphere" PC version from about 1 minute before and after Sprint Detection was engaged.
- [MENU] - [Settings] - [Logging] - [Sprint Detection]
Check the box.
- When the Sprint Detection function is enabled, a "S" icon is displayed on the task bar of the main menu.
- By synchronizing a riders parameters with "Cyclo-Sphere" via Wi-Fi, MMP parameters for the past 3 months of accumulated log data are downloaded.
[MENU] - [Option] - [Wi-Fi Connect] - [Parameter Sync]
