For a little while I've noticed that my bike speed seems to be off what my GPS is showing. So for example, bike thinks it's doing 25kmh but my GPS is showing I'm really only doing around 22-23kmh. I normally only ride with guys on normal bikes so never gave it much thought. But recently riding with a bunch of emtb riders it does seem to be the case, cruising on the flat it was noticeable.
Has anyone had this issue before and is there a way to recalibrate it? Or is there something I should look at, maybe the sensor isn't in the right alignment or something?
