TrialBikes Star Nut

Description and materials
- TrialBikes replacement star nut.
- This tiny but essential part, which is inserted into the steerer tube, ensures the headset bolt has more than enough thread to keep the stem tight.
- The right size must be chosen to make sure it adapts fine to the interior of the steerer tube.
- To choose the right size, measure the fork’s internal diameter and choose a star nut that’s 1 to 3mm bigger than the size measured.
- Available in 4 different sizes:18mm (Small), 21mm (Medium), 23mm 1" (Large) and 26mm (Extra large).
- All different sizes feature a standard M6x1.0 thread.
- Please note: check the Installation guide for more info.
- Sold singly.


Installation guide
- To install the star nut into the fork, we recommend using a star nut setting tool (not available in our web). Otherwise, you can screw a bolt in the star nut and hit it carefully with a mallet; always trying to keep the star nut’s thread vertical since the headset bolt must be screwed smoothly. Thus, the star nut will fit tightly, adapting its shape to the interior of the steerer tube.  Any damage occurred to the star nut or steerer tube won’t be covered under any guarantee claim, therefore we recommend the installation to be carried by a professional.
- If you want us to fit the star nut in your fork, just add the “Trial-Bikes star nut fitting Service” to your basket and the TrialBikes professional team will do the job!
