Description

Take off to an alien world in confidence with this sweet guard sprocket.

Features
  • Guard and sprocket in one. The guard runs out past the teeth, so ledges and rails hit alloy instead of your chainring.
  • CNC machined 7075 aluminium. Machined in full from 7075 alloy at 12mm thick, which is built to take BMX abuse.
  • Offset 1/8 inch teeth. The offset tooth profile improves chain alignment, so the chain tracks straighter through the drivetrain.
  • Fits 19, 22 and 24mm. A 24mm bore with 19mm and 22mm adaptors included, covering the common BMX spindle sizes.
  • 28 tooth, standard profile. Runs a 1/2" x 1/8" chain on either a one piece or three piece crank.

Specifications
  • Spindle: 15/16" (24mm) bore with 19mm and 22mm adaptors
  • Teeth: 28T, standard tooth type, offset 1/8"
  • Chain size: 1/2" x 1/8"
  • Material: 7075 aluminium, 100% CNC machined
  • Mount: 1pc / 3pc crank compatible
  • Note: 12mm thickness. Adaptors for 19mm and 22mm spindles are included.
