I went to tighten my chain today and i loosened the nuts on my rear wheel and pulled the wheel back and tightened it.
Then i put the nuts back on and started riding and realized it was too tight. So i took the nuts off again and loosened it a bit.
But after i put the nuts back on and it was all good i spun the cranks to see if the wheel was straight and it didnt move! I have no idea whats wrong but when i spin then cranks backwards its really really hard to move and when i spin it forward its really hard to. Please help me out and give me some advice on how to fix it. I just got into bmx and really enjoy it so any information would be very appreciated. Oh and i know its not the BB cuz i took the chain off and the cranks spun just fine and freely.
