knocking/tapping from somewhere on new bike
REcently got a new mountain bike (fairly cheap at aabout $200/£150) but have noticed a tapping/knocking sound when the peddles are rotating. Most noticable when rotating forward. I cannot locate anything that is tapping on the frame like wobble cables/chain etc. Could I have crap bearings in the hub of of the peddles? I cannot feel any lateral movement in the peddle cranks when pushing them by hand.
Any ideas most welcome
Cheers
Mark
