I have a Co-Motion Pangea Rohloff. I have had it over 5 years. It is the only bicycle I currently ride. The belt looks like new. For your belt to miss teeth. I believe you would have to ride it in the woods and trap sticks and grind some rocks with it. I say just ride the thing and don't worry about it. You did say you have a spare belt. I never replaced chains until they broke multiple times on one bicycle ride.
