A few years ago I bought a tub of grease at the hardware store...
I've been using this grease for any bike work I've done, on my own bikes and on some flips. Lubing bolts, screws, wheel bearings, headset bearings, stem quills, seat posts, brake cables, you get the picture.
It's called LubriMatic High Temperature Disc/Drum Brake Wheel Bearing Grease. Base type: Polyurea
Should I keep on keepin' on with this stuff or what? I'm leaning towards "It's fine".
