Bike Bicycle Fork Star Nut Setting Tool, MTB Star Nut Tool with 2 Spare Special Screws and 4 Star Nuts , Foundation Star Nut Setter Installation Tool Installer Install Tool (for 1-1/8" Fork Tubes)

To is really necessary to install star nut in forks properly. Just the fact that it came with four new star nuts ($8each from bike dealer) was a great value. Tool was excellent quality & worked perfectly.

Works excellent. Place a length of 2x4 under the headtube, covered in a folded towel. Keep the bottom of your fork lowers off the ground. I placed the other end of the 2x4 on a rubber floor mat, and struck the tool with a dead blow hammer. Works perfect. Any review you read where someone complains that this item is deficient doesn't know what they're doing. Includes 4 star nuts, which is a plus. Also, the o-ring retention built into the design works well. I have never driven a star nut; this made my first attempt come out perfect. Buy it.

I just bought a new Fox fork and needed to install a star nut. My biggest concern was in getting the nut hammered in straight. I looked at others and this looked to be the best one for the price. The PT version was just too expensive since I'll only be using this very rarely. I was pleasantly surprised by how high quality this was. Due to the gaskets on the inside of the tool it slide perfectly on my forks steerer tube without any play or slop at all. It is a extremely precise fit so the gaskets grab a little so you just have to be patient and put it over the tube slightly slow and not just slam it on. I saw some others mention that they used a light coat of grease to help it go over their steerer. I didn't need to use any grease but I can see how that would make it easier if someone was having trouble getting it on their fork. I just used my soft faced mallet and gave it about four or five good whacks and the star nut was seated perfectly. I used a caliper to measure how far down it was in the steerer tube and it was the same distance as the star nut that was in the Fox fork that came with my bike. The nut was straight and everything went smooth. My fork came with a star nut included so I used that but I looked at the star nuts included with this tool and they look and feel as high quality as the star nut that Fox included. I'm very happy with this purchase even though I will barely get any use out of the tool.

It does the job and it's inexpensive. However, an improvement would be to have tabs on the outside of the sleeve it to make it easier to press down on the sleeve and keep it in place while hitting the middle section. Be sure not to put the star nut in backwards, I did. The concave part faces out.

While there are techniques to install star nuts without specialized tools, I didn't want to chance it with my new fork. This tool worked great for me. I was a bit hesitant based on some reviews citing poor tolerances and build quality. The unit I received (November 2024) was well built with tight tolerances, and drove the star nut in perfect alignment. Great value too.

Awesome tool to perfectly install star nut into 1 1/8" standard size steer tube of forks found on most modern mountain bikes. If you're installing a star nut, probably means you've got a new fork so I'd definitely look for one of the tools to help you cut the steer tube before you ruin an expensive fork!

This is one of those tools that more or less fall in to the Pass/fail category for me. Not complex, has a very singular and niche usage, and it either does what it is supposed to or it doesn't. In this case, it does exactly what it is supposed to. In my personal case I used it to set a star-nut in a Manitou mezzer pro fork. Sleeve fit perfectly but a little snug around the steer tube, and the insertion depth using the tool was identical to the insertion depth on my stock from the factory fork. In general the biggest risk would be deforming the silver cylinder (which is why you would usually use a synthetic hammer for this) but even using a metal hammer (I'm lazy, they are faster) the cylinder had no mushrooming at the head. All in all, I can't see *any* reason to buy a more expensive version of this tool for home use. Maybe long term if you are installing hundreds of star nuts it would start to show more wear than a more expensive version, but if you just need something to do work on your home bikes, this will do exactly what you want it to do at an incredibly reasonable price.

Worked great on two Specialized FSR Mountain bikes. Easy to use and hard to screw up!

When I tried installing without this tool, I couldn't do it. But with this tool, inserting a star nut is a piece of cake. Comes with plenty of nuts, too. Don't be alarmed, like me, when it is hard to unscrew after you smashed in the nut. It can take a lot of force to unscrew, but it will come out cleanly.

Great little tool! If you're having a wiggle in your fork, check the fly nut and replace it with this if it's damaged or come loose. I've paid 400 dollars to "mechanics" to do absolutely nothing and then 27 bucks to get this and do it myself. Thanks for the save!

Although not the greatest quality, it does the job it is intended for.

Great tool.. unfortunately… I may never use it again😁
