This is the 20" Rampage Cassette Rear Wheel from Stolen BMX and it comes with some really nice specs. It is the largest wheel in the Rampage series.
It comes with a fully sealed cassette hub, laced by hand, to the 36 holes Rampage double-wall rim. This results in a long-lasting rear wheel that can withstand some hard impacts. Furthermore, it comes with a Chromoly 9T right-hand driver and standard 14mm Chromoly axles, ready for peg installation.
