Azusa Engineering's 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 with your hub.
• 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 is a good practice to replace the chain when you replace worn sprockets and vice versa.
