Agree with you on calibration,...Great explanation. Agree with you on calibration, I will now be calibrating every 6-12months.<br />Alex, have you calibrated Quarq’s?<br />I run 3 Quarqs on different bikes and felt recently that one of my road bikes using an ELSA R was reading lower than my other road bike which has a new DZero. I got a certified 20kg weight and calibrated all three units. The ELSA R was 5% low, the DZero was 2% low, and the Quarq SRAM Red on my TT bike was spot on. Big differences!!! When I reported this to Quarq customer service they recommended against field calibration, stating it was no longer necessary (post Cinqo’s) and claimed the factory slope was better. Thing is, I know they measure inconsistently using the factory slopes. So I’ll stick with my field calibration slopes.<br />Hey, do you know the units of the slope for Quarqs? I believe the units of the SRM slope is Hz/Nm, but that doesn’t seem to make sense for my Quarq slopes.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-35788819.post-62209968361415594592013-06-25T08:01:42.666+10:002013-06-25T08:01:42.666+10:00Since you cannot calibrate a Stages power meter, I...Since you cannot calibrate a Stages power meter, I suggest talking to the Stages people for troubleshooting help.Alex Simmonshttps://www.blogger.com/profile/00698332397074026424noreply@blogger.comtag:blogger.com,1999:blog-35788819.post-92081044317182374042013-06-25T06:11:13.856+10:002013-06-25T06:11:13.856+10:00Installed a Stages crank power meter 4wks ago and ...Installed a Stages crank power meter 4wks ago and it seemed to work perfectly until the crank came off (complete mystery) and since refitting the readings have gone awol despite recalibrating the new Garmin 500 - should I presume the meter has been damaged ?Tomohttps://www.blogger.com/profile/01101338416195641602noreply@blogger.comtag:blogger.com,1999:blog-35788819.post-49366568376649919372013-04-24T12:40:46.575+10:002013-04-24T12:40:46.575+10:00Loving your work AlexLoving your work AlexGlennhttps://www.blogger.com/profile/14174591618638243919noreply@blogger.comtag:blogger.com,1999:blog-35788819.post-80314065142248519572013-02-12T04:08:16.582+11:002013-02-12T04:08:16.582+11:00Very nice explanation.
