Hi there!
I'm new in Serbia and first of all glad to see here such a big bike community. I live in Novi Sad and have with me my commuter bike here as well. And, as it often happens, not everything goes well with the bike. Long story short, I have a planetary nexus 8 hub on my bicycle and recently I have discovered that it has a play in bearing, something about 2mm if measured near the rim.
Usually I do all the repairs myself but gearhub is an exception, i am a bit afraid that I completely don't have any experience in it and definitely gonna break something first time.
So, I am looking for a service shop that have an experience in repairing and servicing internal gear hubs, it you know any in Novi Sad or Belgrade, please share it with me.
