First of all I will start with the fact that I'm completely new to the world of hardware related to bike parts.
But I must say I ride my bike a lot. My everyday commute is roughly 40-50 km. I drive a Pegasus Premio SL belt 2019 and it is a city bike. I bought it almost 6 months ago. As of now, I have rode more than 5km with it. As far as my knowledge goes, it is equipped with a Shimano Nexus 8 speed hub with a Gates CDN S150 belt drive system. I don't know how many teeth I have in my belt (sorry).
Recently I saw that my belt started to chip its teeth away (of course wear and tear). Therefore, I'm planning to switch to a Gates CDX-EXP version to avail myself its robustness (at least that's what the website claims ;)). So, here I am.
I would like to know which combination of sprockets (front and rear) should I use and how many teeth should be in my belt and why. Moreover, I would like to know the meaning of teeth in the sprockets and belt. In addition, I would like to know whether I can use the re-use stuff from my old CDN S150 crankset.
This question is mainly because I tried searching for combinations on google but not with much success (I'm bit lost, because I haven't had much experience with it, yet). I of course read their manual, but it has different combinations and honestly, I'm a little bit lost.
Finally, I would like to have your feedback on whether it is worth upgrading.
