Collection: BMX Sprockets & Chainrings

BMX sprockets and chainrings cover everything from compact freestyle gearing and guarded street sprockets through to race chainrings, spiders, power discs and rear cassette cogs. Blue Groove carries a broad mix of tooth counts, mounting standards and drivetrain styles for freestyle, race, retro and custom BMX builds.

Start with the mounting standard and tooth count, then check crank or spider compatibility, bore size or BCD, chain width and the rear cog or driver you’re pairing it with. Gearing only works as a complete system, so match the front and rear together rather than choosing either one in isolation.
