Match BMX pegs to the exact 3/8-inch or 14 mm axle system, available thread or bolt engagement, peg length and diameter, material, hub guards, and riding surface.

No. Bicycle pegs require an approved axle, hub, fork or frame, dropout, and enough thread engagement. Quick-release and thru-axle bikes usually need model-specific systems.

Confirm the frame, fork, axle, dropout, peg, and riding use are compatible before installing BMX pegs with the correct deep socket.
