Garmin Wheel Diameter Settings
Ever since I have had my Edge 500 I have had the wheel circumference settings mode on "auto", including when using it on my turbo. However, it has just been suggested to me that I should really be using it in the "manual" mode, and then inputting the wheel circumference relevant wheel diameter onto the device, in my case 2105 for a 700c x 25 wheel/tyre combo
Is that right?
So if that is correct, then do you have to keep switching from "auto" to "manual" wheel circumference each time you use it on a trainer?

Or select "manual" and input 2105 and then switch it back to "auto" mode?

Yes, thats exactly what I was thinking Andy to be honest?Andy Terry wrote:Seems to me you can stick it in manual mode, enter the value and leave it.
Worth a a try, maybe.

You can always setup another "bike" on the garmin specifically for the turbo if needed. Ie Auto for turbo but manual for road, that's what i do. all my garmin 'bikes' have manual wheel entries as the roadbike is very different to the cx and I've found the auto to be a little off. It only matters if you're using a speed sensor, if you're just using the GPS to do speed then just leave it on auto for everything.

Yes in theory I would agree with you 100% Chris. However, what confuses me is that I have never ever had my Garmin set on any other setting other than auto, and as you will see from all my turbo sessions on Strava, its picking the speed and distance from somewhere?Patch wrote:If your using auto on the turbo then the garmin won't be able to work it out because your not moving. So it should be on manual for turbo use. I have mine on manual all the time it doesn't affect GPs performance.
Unless as Laurence has suggested, it retains the wheel size settings?
Just as a matter of interest, but when I went out yesterday, I had both my Garmins running again as a test. The Edge 500 was set to manual at 2150 wheel circumference and the Edge Touring set to auto (you cannot do manual anyway I dont think?) The average speed and also the distance ridden were exactly the same when I downloaded both .gpx files.
