The S&M Mid School Guard Sprocket pays homage to the original S&M "Bashguard Sprocket" that came about in 2005. Pro team rider Aryei Levenson has a unique style that has grabbed a ton of attention which led to a re-issue of this sprocket after riding an OG one that people took notice too. 

On this current version S&M widened the crank clearance cuts a little, updated the teeth to a modern profile, and offset the teeth as well for better chain alignment. Additional engraving was added along with three additional colors including a matte purple to match Aryei’s signature frame.

Best part is you don't have to worry about tariffs since it's still made in the USA.
