It's exactly what it says - a hub that has some sort of seal to protect the bearings from dirt and water. IT's not good enough to be called fully sealed, but it's better than an unsealed hub.
A freecoaster BMX is a type of BMX hub that allows the rider to coast backward without pedaling. This differs from a traditional BMX hub, which engages the pedals when the bike is moving backward.
Depends on the bike frame..
No. a 9T sprocket will only fit a cassette hub, and not freewheel hubs.
Probably. Today BMXes can have either a freewheel hub or a cassette hub, but as long as you stay within the hub type you can move parts from one bike to another.
Kinda, sorta. You can certainly (have someone) build a BMX wheel around a fixie hub. I suppose you could somehow disable the freewheeling action of a regular hub too, but I wouldn't recommend it. Putting back pressure on the pedals on a bike that hasn't a real fixie hub can cause the sprocket to unscrew.
To effectively perform a BMX rear hub repair, follow these steps: Remove the wheel from the bike. Disassemble the hub by removing the axle, bearings, and freehub body. Clean all parts thoroughly. Inspect for any damage or wear. Replace any worn or damaged parts. Grease the bearings and reassemble the hub. Adjust the hub to ensure smooth rotation. Reinstall the wheel on the bike and test the hub for proper function.
The standard BMX hub spacing measurement for most modern BMX bikes is 110mm.
When choosing a rear BMX hub for optimal performance, key features to consider include the hub's material and construction for durability, the number of pawls and engagement points for efficient power transfer, the hub's compatibility with your bike's frame and drivetrain, and the hub's weight for better handling and acceleration.
When choosing a BMX cassette driver for your bike, consider the number of teeth, material, engagement points, and compatibility with your hub. These features affect the performance, durability, and smoothness of your ride.
You need the right kind of hub for that. If you haven't, buying a new rear wheel - with the right kind of hub - is probably the sensible option.
Yes you can.... you can put any hub, spoke, and rim combinations together...maybe a few ecceptions but you can deffinetly do that... just bring the parts to your local shop and have them lace it.
If you have a flip-flop BMX hub, you can put a 14T on the smaller diameter side of the hub. If you have a cassette hub, you can get as small as 11T.
