Got a set of Superstar wheels with cartridge bearings. What grease is best to use, ive got weldtite lithium grease the white stuff, it looks like that has been used in the hubs already as it's turned into a grey paste. Is it better to use a teflon grease? Oh and how much should I throw on.
Thanks.

I've always used park Polly Lube ( http://tinyurl.com/p738jq8) in shimano hubs and it seems to hold. Where are you using grease in cartridge bearings?
"Grease packing to approximately one quarter to one third of a ball bearing’s free volume is one of the most common methods of lubrication. Volumes can be controlled to a fraction of a percent for precision applications by special lubricators. In some instances,customers have requested that bearings be lubricated 100% full of grease. Excessive grease, however, is as detrimental to a bearing as insufficient grease. It causes shearing,heat buildup, unnecessarily high torque, and deterioration through constant churning which can ultimately result in bearing failure."
"To lubricate threads never use lithium based greases."

Agreed with the weldtite stuff I rarely use it on bike bits although it's good for sliding greenhouse doors
For hubs I like Shimano's finest. Luminous green, smells good and doesn't stick to your fingers
I pack my bearings with the finish line Teflon stuff. Pretty handy with the tube and applicator, seems to keep the bearings running smoother for longer. That post about heat build up and added torque, is it based in the likely rpm and conditions on an mtb? Surely the main reason for failure on an mtb would be from ingress of water? So the addition of grease will help to prevent this and is a worthwhile trade off?
CV grease from a car place, 1kg tub will outlast me. I use either that or copper grease for threads on my bike, bike specific products are just five times the price.
Ive used this for ages it seems very good
