Hi, here you can find info about great longboards wheels.
Yep these urethane ones you see under the longboards all around.
If this are drop down longboards, drop through longboards, kicktail or pintail longboards, they all have wheels.
For different riding styles and activities you might want to use slightly different wheels. Will provide some info to help you better tune your board setup.
Hope you like it.
