To install, carefully remove the old downtube guard, clean the surface removing any dirt or adhesive residue (with some isopropyl alcohol or similar), remove the adhesive backing (without contaminating the adhesive pad with greasy fingertips) from the guard, and lightly affix in a desired position, preferably at room temperature or above. Please refer to the Dreadnought exploded view document for our alignment guide. When you’re happy with the position, apply some pressure to the guard and you’re ready to shred.
