All skateboard bearings will fit ANY sized skateboard wheel because the bearing hole is designed to be the same in all wheels.
yes
Almost. I've seen a horribly cheap toy skateboard once that didn't have bearings, only a plastic center to the wheel. But apart from that, any time you buy a complete skateboard it'll come with bearings.
If our talking about a blank deck then no. But if your talking about a pre built complete all bearings will usaully suck for that so say away from pre built completes make your own with bones bearings
All 8 that should be in the wheels.. (2 per wheel.)
A complete skateboard is all the components of a skateboard already set up and ready to ride. Most skate shops sell completes, but most people like to build there own, that is to buy all the components (deck, trucks, bearings, wheels, hardware and griptape) and then assemble the board themselves.
a Complete Skateboard is a fully assembled deck, wheels, trucks and grip-tape ready to for you to skate. Often, complete skateboards (called "completes") have most of their parts from one brand, and there are a lot of good quality completes out there. There are a lot of brands, shapes and sizes of complete skateboards available on the market. Knowing which one to buy could overwhelm you to the point of giving up! The key points to establish before going shopping, is to make a discussion on what kind of skateboard you are after: A classic skateboard, a long-board or a street/vert board. Here, I will try to explain and help you in finding what kind of skateboard you after and what skateboard brands are out there. Good Luck!
Actually There are definitely trucks 7.65. Get those they are the closest.
Depends on what trucks,wheels,high-rises,bearings,and deck you get. An amazing website to buy skateboards from is CCS.com they have a magazine that you can have ordered to you too. You build your skateboard right on the website and you get discounts for buying a whole board and all kinds of stuff.
yes
Use a wire brush or sandpaper, maybe a cloth with some WD40 or alcohol. I soak bearings in rubbing alcohol to get off all the grit.
Depends on what you think of as cold. The type of bearings that skateboards use are basically an industrial standard bearing you can find in all sorts of machinery. They'll run just fine at any temperature a sensible human would be interested to go skateboarding in.
