Can I put an 11 speed cassette on a 7 speed hub?

Do all cassettes fit all hubs?

Most cassette hubs are compatible with Shimano cassette cogs. SRAM cassettes and most Miche, IRD and SunRace cassettes use the same inter-sprocket spacing as Shimano, but at least some SRAM 10-speed cassettes do not fit aluminum-body Dura-Ace hubs.

Is cassette better than freewheel?

Removing the freewheel is one of the main drawbacks of this system as the high torque from pedaling tightens the freewheel to the hub. The bearings are closer together, which equates to lessened leverage compared to the cassette (the cassette is stronger)

Why would you want a single-speed mountain bike?
