Andy_P Posted March 12, 2020 Share and if you stop to calibrate? does that change things at all? i have noted that power readings are suspiciously low. i MUST be putting out more. Surely? Calibration does sort the issue out yes, but I don’t always have the legs to get back in the bunch! lechatnoir 1 Link to comment Share on other sites More sharing options...
Andy_P Posted March 12, 2020 Share They don't have temperature compensation - hence the issueI watched a TrainerRoad podcast where 4iii Product Manager Scott Cooper said that they do have active temperature compensation... interesting... Link to comment Share on other sites More sharing options...
Job Posted March 13, 2020 Share My road bike 4iiii PM lasted for about a year and a half working perfectly before it started to give me higher readings. I was averaging 300W during Amashova race last year and I thought my training was paying dividend , yet I wasn't getting ahead of the bunch. I later realized that it was over reading. But I must credit the 4iii local agents for swopping it for me. I have been on a new one now for 3 months and I am still happy thus far.

Schnavel Posted March 13, 2020 Share I watched a TrainerRoad podcast where 4iii Product Manager Scott Cooper said that they do have active temperature compensation... interesting... That must be the new units that now have temperature compensation added. Previously, this wasn't the case. The Spez dual sided powermeter was developed with 4iiii a year or two ago and Spez insisted on having temperature compensation, which at the time, wasn't part of the 4iiii system. I'm assuming that since then, the newer 4iiii units now have temperature compensation Link to comment Share on other sites More sharing options...
DamoCPT Posted March 13, 2020 Share I really think its the luck of the draw when it comes to power meters.... its like a lucky packet... I've had my 4iii for a year and a bit on the road bike with no issues at all. Power readings are closely matched with my Elite smart trainer.

If you need to stay with the bunch, rather watch their wheel than your power... DieselnDust, Dexter-morgan and Veebee 3 Link to comment Share on other sites More sharing options...
