- Replacement star fangled nut for use inside fork steerer tubes to allow pre-load of headset bearings.
- Standard M6 x 1.0 thread.
- Available in various sizes: Extra Large (26mm diameter), Large (23.5mm diameter), Medium (21.0mm diameter) and Small (18.0mm diameter). Dimension is of the star nut itself before fitment.
- To check which size you need, measure the internal diameter of your steerer and choose a star nut that's 1-3mm larger than that size.
- Extra Large generally fit 1 1/8" steel steerers, Large 1 1/8" standard alloy steerers, Medium are for use in Echo 1 1/8" alloy steerers and Small ideal for Inspired Fourplay or Team/Trialtech Sport forks - but please measure to be sure!
- Sold singly.

Please note that star nuts are designed to be a tight fit so they don't pull back out when you tighten your headset. We strongly recommend using a star nut setting tool for fitting, or alternatively you can screw a bolt into the thread and then carefully tap the bolt to install. Damage to the star nut during fitting is not covered under warranty as these do not 'just fall apart'! Similarly, the warranty does not cover instances where the headset top cap bolt has been overtightened.

If you are buying forks and a star nut and would like us to fit it for you, add a Star Nut Fitting workshop item to your basket.

If the star nut is listed as 18mm, does that mean its for an 18mm ID tube? Or is it 18mm when compressed ? I want to put one into each end of my bars to hold a mirror, and the bars have an ID of 16.5mm. What do you think ?

Hi - The star nut itself measures 18mm without having been fitted. If your bars have an ID of that size, the Small star nut will work. Thanks.

very helpful

So much less hassle than cutting down a big one!

Hi Ash - They're certainly a handy addition! Thanks for the review.

Again just an odd little sod that you need. :D Thanks guys!!

Hi Callum - It is handy having the sizes needed for trials forks - they can sometimes be pretty tricky to get hold of from regular shops due to them being an odd size. Thanks for the review!
