Trainer software updates have gotten complicated with all the ERG mode tweaks and firmware versions flying around. As someone who spends way too many hours on the trainer, I learned everything there is to know about this Wahoo update. Today, I will share it all with you.
Wahoo pushed a software update for the KICKR series trainers that improves ERG mode responsiveness during interval workouts. Version 6.2.1 addresses lag that some users experienced when power targets changed rapidly.
Probably should have led with this section, honestly.
The update applies to KICKR v5, KICKR v6, and KICKR CORE models. Installation happens through the Wahoo app on iOS or Android. The trainer must be connected and spinning during the update.
ERG mode changes now take effect within 2-3 pedal strokes instead of the previous 4-5 strokes. That’s what makes this update endearing to us structured training enthusiasts — the accuracy improvements for short intervals.
Wahoo also added a new “Fast Response” toggle in advanced settings for riders who prefer even quicker adjustments, though this can feel abrupt during longer efforts.
The update is free for all compatible trainers. Users report the improvements are immediately noticeable in structured workout apps like Zwift and TrainerRoad.
