Collection: BMX Cranks

BMX cranks need to match both the rider and the drivetrain. Blue Groove’s range covers shorter youth race cranks through to full-size freestyle and race setups, including one-piece, square-taper, two-piece and three-piece systems across a wide spread of crank lengths and spindle standards.

Start with crank length and intended use, then confirm spindle diameter or interface, bottom-bracket standard, sprocket or chainring fit and drive-side requirements. A shorter crank can improve clearance and suit smaller riders, while the spindle and mounting system determine whether the crank will actually work with the rest of the bike — so check the whole setup, not just the arm length.
