You probably didn't know, besides the chain,
that there were other areas that need greasing
on a regular basis on your bicycle.

Items required:
- grease fitting, drill bit, drill, wrench or small socket
- small bolt with same thread as grease fitting
- grease gun

First
Flip a bicycle over, seat down, pedals up.

Drill into bicycle frame
Second
Drill a small hole, slightly smaller than the grease nipple thread. Keep the drill hole away from left side 3/4" (2 cm) so as not to drill into the bearings.

Third

Screw a bolt into the hole that has the same thread as the grease nipple. Work around good and remove.

Forth
Screw in the grease fitting using downward pressure. Get grease gun and pump about 20 pumps worth of car bearing grease into empty crank shaft area.
