Step 1: Identify the parts
Note that the nut for the seat stay bracket is usually already pressed into the bracket, but it occasionally comes loose in shipping and needs to be placed back in the rear bracket.
Step 2: Put the shims inside the brackets
Note that the nut for the seat stay bracket is usually already pressed into the bracket, but it occasionally comes loose in shipping and needs to be placed back in the rear bracket.
Step 3: Attach the down tube bracket
Wrap the down tube bracket around the down tube with the holes for the screw facing down and the nub that attaches to the chain guard facing the chain ring. Put the nut and screw in place, but keep the bracket loose so it can be adjusted later.
Step 4: Attach Rear Bracket
Wrap the bracket around the chain stay. Make sure the screw hole faces up and the side of the bracket with the nut is on the inside of the chain stay (towards the wheel).
Step 5: Attach chain guard to brackets
Insert the nub on the down tube bracket into the slot in the front of the chain guard.
Position the hole at the read of the chain guard inside the rear bracket an insert the rear bracket screw.
Step 6: Position the chain guard and tighten
Move the brackets and chain guard until the chainguard is properly positioned on the bike. The chainguard should sit close to the chainwheel. Make sure that the chainguard is positioned so that it does not interfere with pedal, crank and/or chain operation. Tighten the bracket screws.
