This sprocket first appeared in the S&M 2005 lineup as the ‘Bashguard Sprocket’ available in 33t, and then simply as ‘Guard Sprocket’ in 2006 when it began being offered in 25, 28, 30, 33, 36 and 39t.

Fast forward to June 2024 when S&M Pro Aryei Levenson started riding a used 33t he got from Shad at Goods BMX and single-handedly created the demand that led to this slightly updated re-issue.

On this current version S&M have widened the crank clearance cuts a little, updated the teeth to a modern profile, and offset the teeth as well for better chain alignment.
