On my last two ascents of Innsbruck climb my smart trainer has lost power and cadence about 400m from the finish. Ive been going for PBs on both occasions so this is incredibly frustrating. Its never happened on any other ride or any other segment
I’m sorry to hear that you’ve had some troubles with power and cadence drops. While it’s not impossible that there’s a direct correlation between the fact that your smart trainer experienced a power and cadence drop and the fact that it happened at approximately the same segment of the same Innsbruck route consecutive times, it could also be coincidental and symptomatic of a different issue with your setup.
