JasonW Posted March 25, 2008 Share While we are on this topic' date=' is there any benefit to the use of copper slip?[/quote'] Yebo. Seems the 'dales previous bike shop used copper slip on the axle of the BB and the Si cranks. It does seem to work well on pedals and is a lot less messy. Expensive though.

Johan Bornman Posted March 25, 2008 Share OK' date=' then I'm cool (carbon seat post and new a-headset thingy). But using a bit of grease on bottle cage bolts? That not good or OK to do?[/quote'] On bottle cage bolts it will be ok, since there is no movement there that "pumps" water, but I won't bother. Don't assume your carbon post won't freeze. If the frame is aluminium you may still sit with a stuck post. Link to comment Share on other sites More sharing options...
Johan Bornman Posted March 25, 2008 Share It does seem to work well on pedals and is a lot less messy. Expensive though. No, it costs about R38 for a 100ml tube, which will last the average DIYer two lifetimes. I wish it were available in smaller tubes. Link to comment Share on other sites More sharing options...
Johan Bornman Posted March 25, 2008 Share How often are you meant to grease up? Your question is not quite clear. I'll try and cover all bases. It depends on mileage and conditions. If you ride often in the wet, it pays to just open your bearings and have a look for contamination. It is easy to see - your grease would have changed colour. If you want to prevent seatpost freeze, loosen it every few weeks in the riding season and wiggle it. If you wash it often, or ride in the rain, do it more often. It is quite easy to diagnose water contamination in wheel bearings without opening the bearings. The day after the contamination, you'll experience a crackling sound, like cellophane sweet wrappes being opened, coming from the wheels. This means water got in and formed some rust. What you're hearing is the iron oxide crystals being crushed by the bearings as they roll. The sound is quite distinctive, if difficult to pinpoint directionally. Trust your instincts, if you hear it, clean your bearings after that ride or you could ruin your hubs. With pedals and the like, grease whenever you remove them.

Johan Bornman Posted March 27, 2008 Share Ok silly question' date=' what is the difference between grease, oil, chain lube and chain wax? [/quote'] Oil: A lubricant that is liquid at room temperature. Special oils will remain liquid at a wide range of temperatures and more or less maintain its viscoscity - particularly engine oils. On a bike, you'll use this on your chain. Grease: A lubricant that's a semi-solid at room or operating temperature. Actually just a bit of soap encapsulating oil. A grease cannot flow back after it has been pressed out between two surfaces but thanks to the movement of the two surfaces, it usually glues itself back into place. Also, the very last molecule is extremely difficult to remove, therefore high pressure isn't all that big a problem, especially in bearings that tend to relubricate themselves due to the rolling action of the balls. ON a bike, you'll use this on your wheel and BB and headset bearings. Wax: Not a good lubricant. It doesn't flow back nor does it self-smear. It tends to flake away once disturbed from its surface. On a bike, it is best used on the legs as a hair removing agent. Link to comment Share on other sites More sharing options...
