The whole thread begs the question, what do you use a compass for on a bike ?

I can understand on a mt. bike while exploring a maze of forest trails or roads, but maybe not on a road bike. Even following dirt roads, you typically know, mostly, where you are and where you are headed, IF you have a map that you studied in advance (which is how you are where you are in the first place)

Seems its like when you are hiking, you probably would be following a trail. So not using compass much, but carry one anyway in case you have to bushwhack around blowdowns, beaver ponds, etc... then you want a compass with you for that just in case moment.

But on a bike you kind of need to stick with a trail or road, as you really can’t take detours easily. And every time I was “lost” while exploring in New Mexico it was always a case of just getting detoured on the wrong dirt road. I was never really “lost” as all I needed to do was go back the way I came.

So I’m curious as to how the OP plans to use a compass, while riding a bike and I’m not stating there’s not a need, just curious as to how others might use this.
