So its almost been a year since ive owned the freemix, had to replace some bearings several months ago and it ran great till today, i saw that i needed to adjust my chain so i went got it nice and tight, as soon i started riding it felt completely off like the hub got hard to pedal almost, and then i started not being able to pedal at all, and then it would work for a while and then start it again, i went home took it apart, and saw nothing out of the norm, no metal shavings either, so i figured maybe it just needs to be lubed again, did that and it ran great for a couple hours, then i tried some feeble hard 180s and then it came back again, is it just time for a new hub? Or is this somehow possible to fix, and from where im from bike shops dont know shit bout bmx let alone a freecoaster
