every once in awhile my freewheel skips under load. would this be a symptom of sticky freewheel pawls, or perhaps an under tensioned chain? chain is new, freewheel is stock from an 08 bike but the teeth aren't looking too sharky. think a mega blast of wd-40 is a good start?
new freewheel new chain 'teeth not to sharky' indicates it's worn none the less , replace both together .
chainring wear also in question .. get all 3. change the gear ratio at the same time with the tooth count selection.
