Hi there, just trying to find out whether many others are having issues with their Assioma Duo. Been using mine out on the road now for around 18m and have enjoyed trouble free operation until the last week or so. I am now finding that I am having spells of under-reading and spells of over-reading - seemingly accompanied by big swings in L/R balance, though with no clear pattern.
For instance I calibrated before a ride this morning and found that overall average power for the ride was around 15-20% less than I would have expected and with an overall average L/R balance of 45/55 (I am used to seeing anything from 50/50 to 47/53 but not 45/55). This is actually an improvement on my previous two rides which had much bigger discrepancies. I then recalibrated after a coffee stop before a 20min ride home which finished with an average L/R balance now skewed heavily to the left at 57/43.
I have seen other erratic behaviour in my previous two rides - on the first problem ride I had half the ride with a power reading an estimated 20% under perceived effort and then following a mid ride re-calibration finished the ride with power reading an estimated 20+% over (for which TR awarded me some “best all time” trophies which was nice) and with average L/R balance skewed as much as 60/40 for significant spells.
During the last week (and after the first problem ride) I have updated to both the current Assioma firmware and the new Edge 530 firmware, but this did not fix the problem. Also I have always followed the same routine of calibrating (carefully) before each ride - and have swapped the pedals between bikes a number of times without problems (and in fact did so this week between two or the problem rides).
I have seen on a thread on dcrainmaker’s site that he has relatively recently started having issues with two different pairs of Assiomas which he has currently shelved until he gets chance to investigate. I might have this wrong but I gather one pair is a pair he has used previously without issue, and the other pair is a new pair. Could be entirely unrelated coincidence of course.
I have submitted a request to Favero technical help a couple of days ago and am currently waiting to hear back from them but thought I would see how others are getting on in the meantime.
