I've had my Edge 25 for a while now, but I still can't use it on my turbo trainer because it seems that there are no straight bits of road anywhere nearby that are long enough so I STILL don't have a wheel size.
Is there any hope of a firmware update that allows wheel size to be set? If not then I think I'll have to return this device for a refund as it's clearly not fit for purpose.
Why Garmin? Why not offer the basic ability to manually enter a wheel size?
