First real ride with a new Quarq Elsa. After a 10 minute warmup I settled into a couple of very steady 20 minute efforts around 85rpm cadence. No deviation during the 20 minute intervals. Below is the Golden Cheetah plot of the ride. You can see where the cadence drops very low very frequently and this of course affects the power. At the 1-hour mark I do some hard short starts as is recommended with a new Quarq. The last 15 minute steady effort had tons of cadence drops.
The cadence magnet is secured in line with the dotted-line on the inside of the crank and is very very close.
I don’t suspect any wireless interference as the HR signal was completely steady during the ride. Also, I previously had a Quarq S975 on a different bike and never had issues riding the same trainer in the same room under the same conditions.
check your firmware version, most likely it is 19, but if it is not that was common on previous version of firmware. 19 has been out for quite a while now, so not sure how you would not have it.
I will do that. Just to help me understand. If I’m riding steady indoors, and the cadence is fine for several minutes varying only 1-2 rpm for every reading, and then it drops 30 rpm for an entry or two even though I’m still riding at the same cadence, this doesn’t sound like a magnet issue, correct? I would think that if the magnet was an issue and I was riding indoors, I couldn’t get any period of time where it would be steady.
Quarq to Garmin and then downloaded to GC. I previously had a Quarq S975 that I used the same way. I don’t think there’s any interference because the S975 never had an issue and the HR monitor on this ride had no issues.
