Tp4's exercise bike pedal needed lubrication.
Good news, as it's indicative of dat Tp4 is getn' z xercise. Ball bearings, Still a tiny hint of scratchiness, but overall acceptable, no need to be nit picky, still wurks gud', less pollution.
COULLLD take the whole thing apart, and grease it properly, buhhh, the problem is the little plastic cap on the end, Tp4 feels like, if he pops it, that's like the end of it, prolly won't go back on.
