I'm brand new to the world of belt-drive bikes so trying to understand what's normal and googling isn't helping with this specific question.
One of the selling points of belt drives is low maintenance and less stretch than a chain. However, after just a couple of days and only 10km my belt is feeling pretty loose - not skipped yet but just feels/looks too loose, and is looser than bike was out of the box.
My question then is does this indicate an issue with the belt / build (having left eccentric BB pinch bolts loose for example) or is it just one of those things that has to be done once/early after bedding in then much more rarely after that?
This question points to someone who had a very similar experience to mine - on a very similar model of bike (mines a Cube Travel Pro 2022, XL frame). Is it normal/expected?
=== EDIT: having done some more investigation (and gotten the Gates belt tension app working vaguely consistently) - I now think the tension has not changed since I first got the bike, but instead there is a 'tight spot' as the pedal crank is turned. In ~30-degrees of pedal position, belt tension is about twice what it is anywhere else (~40Hz in the tight spot - which is within accpetable range, VS ~20Hz everywhere else which is too loose). This same issue is discussed in this question. I suspect it just so happened when I first felt the belt when I first got the bike it was in the tighter spot.
I might need to modify title of this question - or ask another, but this raises two things:
Is this level of tension variation with crank rotation normal/acceptable? (It rides/sounds all good for now). If not I will follow some of the answers to question linked above.
If it is acceptable (or I can't fix it) - I guess my best bet is to have the tension in the loose majority of crank positions close to the bottom of the recommended range (the tight spot will then be slightly above the max recommended value).
