Primo Griffin Guard sprocket
Best durable guard sprocket for aggressive street BMX riders.
This is the ultimate insurance policy for street riders who punish their drivetrain. By prioritizing a heavy-duty, bash-ready design, it sacrifices lightweight performance for pure, unyielding longevity. It’s a set-it-and-forget-it upgrade that ensures your chain stays protected regardless of how hard you case your tricks.
