MTB Wheel Bearing Grease

Best comment was from Old Johan

 

"Use any old grease you can buy at Midas. Bikes don't require special grease anywhere. The exception is Chris King hubs on the ring drive.

 

No need for Marine grease since we don't have to protect our Jhb bikes against salt spray or salt water intrusion.

 

And, there is no such thing as waterproof grease. "

Any grease you can get at Midas or any motor shop

 

I think you would be wrong here - different viscosities of grease exist - you want something between 1.7 and 2.0 - can't remember what the scale is called anymore, but you will be mostly good within that range for low speed bearings on bicycles.

 

For mtb's remember to pack cartridge bearings fully with grease - for road bikes cartridge wheel bearings, not so much is needed - 1/3 - half full is about right - you need to eyeball that...

Thanks, but after 15000 km of using ANY kind of grease on all my components, no problems so far. The most important thing is to regularly service your bike and when doing that the old grease gets cleaned of and you put new ones on/in.

 

But each to its own I guess. Lots of times I sommer used grease we buy at our work in 15kg cans. No problems so far

Absolutely - regular servicing is the way to go - most commercially used grease seems to be between 2 and 3 - so chances are you are in the right range anyway - but there are a few extra sticky types around you don't want to use in a wheel bearing - but would be better than old dirty grease. The very light greases just run out of the seals and make a mess - and self empty the bearing - but again - better than old/dirty/nothing.

 

I am personally a krytox grease fan for certain applications - but that would be overkill in a big way on a bike - notwithstanding the fact you could actually buy a bike for the price of 500ml of it - but it for sure does work better than anything out there for very high stress applications - like race car cv joints... or big ball mill bearings...

What did Old Johan sagest for Chris King hubs out of interest?? seeing as he is in freezing Scotland and can't speak for himself!!

doesn't easton wheels have cartridge bearings?

 

Most wheels have sealed bearings nowadays - notable exception is Shimano - they still claim bearing races have lower friction.

 

The theory on sealed bearing is "throw them away and put new ones in" - in the real world we pop the seals off with a small electricians screw driver and repack them. The steel surface are heat treated and blerry (techhical term) hard. Surfaces only wear out after 10,000,000km. Changing the grease works 100s.

Don't know, don't have Chris King hubs, but go look trough the thread that BigBen suggested. Maybe he said it their somewhere.
