I have a Gates carbon belt drive on a NuVinci hub.
I haven't bothered with the the whole tensioning using the app and everything, but I have a set-up where it is perfectly quiet and I've never had it skip. But the belt feels quite loose.
My question is whether there is any benefit to higher belt tension apart from preventing skipping? It seems the belt does not stretch and too high a tension causes all sorts of problems like bearing strain, noises etc.
So is the ideal tension then the tension that's just high enough to prevent skipping but no higher? Or is there some benefit I can't think of tensioning past that point which is what the app/tools etc. attempt to do?
Thanks in advance!
