FSA MegaExo Plastic Crank Spacer – 24 mm

The FSA MegaExo Plastic Crank Spacer for 24 mm spindles is the thin spacer used together with the wave spring washer on the non-drive side of FSA MegaExo cranks – it sets the correct spacing between the bottom bracket cup and the left arm so the crank sits without play.

Why the right spacer matters

• Correct spacing. Together with the wave washer it fills the gap between the cup and the left crank arm.
• No clicking. A missing or worn spacer is a common cause of a clicking crank.
• Small part, quick fix. A cheap spare that saves a trip to the shop.
• Original FSA part. Made for the MegaExo 24 mm system.

Where does it go?

The plastic spacer is part 3 – on the non-drive side of the spindle, next to the wave spring washer (2).

1 – bottom bracket (two bearing cups threaded into the frame), 2 – wave spring washer, 3 – plastic spacer, 4 – left crank arm, 5 – crank bolt, 6 – drive-side crank arm with the 24 mm spindle, 7 – chainring or belt sprocket (direct mount).

When do you need it?

• The original spacer is gone. Lost, cracked or worn thin.
• You service crank and bottom bracket. And want fresh small parts.
• You run a workshop. A spare on the shelf for FSA 24 mm cranks.
