Yesterday I was trying one of the excercises on The Sufferfest, and while sprinting in one of the intervals (https://www.strava.com/activities/3122063912/analysis) I heard a metallic noise, and after checking around, the Rampa unit was not reporting power anymore, the resistance can be controlled via my garmin unit (Using level mode, and works pretty well), but unlike in the past, I cannot turn on the trainer by pedaling anymore for example... and again, it doesn't report power or cadence over Bluetooth with the computer or ant+ (on garmin) as it did before

Any idea on what I could do, or what's the spare part that I should need? I might try dissasembling the unit somewhen next week, but a hint would be great.
