Wolf Tooth Precision Headset Spacers are machined aluminum rings that set stem height on a 1 1/8 in steerer. Choose 3, 10, or 30 mm in black.

What it's for

Headset spacers stack above or below the stem to raise or lower your handlebar and to fill the gap between the headset and the top cap. Swap sizes to fine tune bar height without cutting the steerer.

Features

• Laser marked: the height is marked on the end of each spacer, so you can tell them apart in the parts bin
• Machined: 6061-T6 aluminum with an anodized finish

Compatibility

• Fits: steerers that are 1 1/8 in at the top. That includes straight 1 1/8 in steerers and tapered 1 1/2 to 1 1/8 in steerers.
• Does not fit: 1 1/4 in or 1 1/2 in upper steerers. Trek Knock Block frames use a separate Wolf Tooth spacer.

Sizing and fit

• 3 mm: 2 g
• 10 mm: 5 g
• 30 mm: 13 g
• How to check yours: After stacking spacers and stem, the steerer should sit a few millimeters below the top of the stack so the top cap can preload the headset. Follow your stem and fork maker's limits for total spacer height.
