I have a repeat issue with long group rides (+1hour 30 mins) where my power freezes/locks at a certain output. I cannot be 100% sure but it looks a pretty consistent timing (after about 1 hour 35 mins) and happens 30-50% of the time: The power locks at whatever the power output was at that point. I can of course finish the ride at constant displayed wattage (sadly not joining the final sprint!) provided it locks at a reasonable power, or I can choose to reset (generally losing about 1m 30s and therefore being dropped from the draft/group).
A) has anyone come across this, and is there a known trigger or fix
B) is there a reliable faster reset mechanism - i can recover up to 30 seconds, but not 1m 30s!
My kit is Wahoo Kickr (original) plus Wahoo HRM direct to bluetooth on ATV, with Wahoo cadence onto iPad running companion.
