Aluminum .125" (6) 1/4" bolt holes.

Premium heat treated aluminum. Root split for perfect alignment. These quick-change split racing sprockets are the finest available. With proper care and mounting they will deliver trouble-free service and maximum wear. Always keep the sprocket halves together. Do not use one half of the set with halves from another. Mark sprocket sets in some manner (e.g., a center punch to make series of dots, etc.) so they cannot be mixed.

Install the sprocket halves onto your hub using the hardware provided. Finger-tighten all hardware and then wrap your chain around the entire circumference to insure proper seating. By carefully tightening down the mounting hardware and then removing the chain, the sprocket should be perfectly aligned. It's a good practice to replace the chain when you replace worn sprockets and vice versa.
