Hubs - basic question vol. 1

[retrorb]

Guys,

Still learning...

I know what a sealed and unsealed hub is but what is a flip flop and what are the pros/cons?

Cheers
Rob

flip flop hub is a hub that is threaded on both sides. one side is generally for a freewheel 16t and up and the other side is for smaller freewheels from 14t - 13t. but i'm no expert.
