What is a star fangled nut?
The star fangled nut — or ‘star nut’, as it’s known — is pressed into the steerer tube and allows the fork and headset components to be pulled into place in the frame’s head tube. If you have a new fork or have just cut down your steerer tube, you may need to fit a new star nut.
Do forks come with star nut?
Typically forks do not come with a star nut. New headsets do, though. Your LBS should have a new star nut for you to shove in there.
Can you use a star nut on carbon forks?
Never use a star nut with a carbon steerer tube fork (Figure 7). Star nuts can only be used with aluminum steerer tube forks. Use only a compression device designed for carbon steerers.
How tight should a star nut be?
Just snug it up. The tighten the stem bolts, but not enough to deform the steerer tube. The top cap will not hold on the stem/handlebars.
How far down should a star nut be?
Star Nut Installation with TNS-1 The TNS places the nut about 15mm (9/16″) below the top of the steering column. This allows the adjusting bolt to thread fully into the nut for adjustment pre-load. It can also help maintain alignment to use the stem as an alignment guide.
Do you need a star nut?

Can you ride without a top cap?
Is it OK to ride without a headset top cap? Once you have your headset in adjustment, you can remove the top cap, bolt, and any spacers above the stem without experiencing a drop in performance or longevity. But of course, if you want to adjust your headset, you’ll have to replace those parts.
How tight should headset cap be?
When tightening the headset top cap it MUST push down on the stem, or the spacer above it, and not the fork column itself (the top cap pushes down on the headset which tightens it up). Do up the headset top cap until it is just tight — at this point you should be unable to turn your stem spacers. Do not overtighten it.
What size star nut do I need?

How does expander plug work?
The expander plug reinforces the area the stem clamps to and prevents damage to the layers of the carbon fiber (Fiber layers can also loosen over time especially with repeated tightening and loosening of the stem clamp).
Can I reuse a Crown race?
yes tap carefully, and it’ll come off fine.
What is the bottom bracket on a bike?

What is a quill stem?
Quill stems The quill stem requires the threaded steerer tube of the fork to extend up through the headset but not protrude beyond it. The quill stem fits down into the inside of the top of steerer tube and is held in place by either a wedge-shaped nut and bolt or a cone-shaped expander nut and bolt.
What is the head tube on a bike?
The head tube is the part of a cycle’s tubular frame within which the front fork steerer tube is mounted. On a motorcycle, the “head tube” is normally called the steering head. On bicycles the manufacturer’s brand located on the head tube is known as a head badge.
