Bike Bearings
doo you need a certain kind of grease for bearings and all that for a bike?
im trying to open like a bike shop kinda thing,and i was wondering if like any kind of grease or lube will work for bike bearings and the handlebars.? help?
To answer your question, here is a basic list of lubes for bikes...
1) Chains and external drivetrain parts, brake levers, shifters- light machine oil (NOT motor oil) or appropriate silicone or parrafin based lube depending on riding conditions;
2) Bearings (roller): if exposed to the elements (like the top of a cable detangler), use silicone based oils or something that is easily washed out and replaced. If protected (like hubs), use white lithium grease. NEVER "pack" the areas full of grease... once clean, wipe in a thin layer of lube on the cups and cones, then roll each bearing around your fingers to give that a thin coat and install;
3) Sealed bearings- NEVER try to lube a sealed bearing. Most have seals which deteoriate when exposed to foreign lubes or degreasers;
4) Cables- apply a thin layer of white lithium grease on exposed cables. Do NOT lubricate inside housings... most have a teflon or delrin sleeve which will soften and get sticky if exposed to lube. Best option is to use stainless cables and forget lubing the cables altogether;
5) seat post, handlebar stem to steerer- if METAL, use white lithium grease inside the seat tube before installing seat post, or when installing stem in (or on) the fork steerer. If carbon/carbon or carbon/metal use the specially prepared assembly grease.
Um, how can you open a "bike shop kinda thing" without good knowledge of bike repair?
Lubricants are a FUNDAMENTAL part of repairs and it scares me a little that you want to work on other peoples bikes and put them at risk without knowing your stuff.
I assume you mean the headset when you refer to the "handlebars". Another fundamental part of bicycle repair is that you know what the parts are called and how they might differ between bikes.
I strongly suggest that you spend some quality time with your bike and maybe some $10 junkers found at yard sales to practice on before you get yourself into trouble.
