The Kool Stop Tire Bead Jack is an articulated tool, with a comfortable grip, for installing really tight tires. The articulated end uses the rigid piece against the rim edge as a fulcrum while the hinged end lifts the bead up and over the opposite edge of the rim. This is a great tool for dealing with difficult tires.

Great tool to help me get my Gatorskin tires on my wheel!
by NVBiker
Cycling Enthusiast
Reno, NV

Recently, I purchased some new Zipp wheels that made mounting tires, like the Gatorskins, extremely difficult . I am a 54 year old female with sort of small hands, but I've always changed my tires myself. When I got the new wheel set I was frustrated that I couldn't get the darn things on. (The last bit was a @#$*&!) However, this tire bead jack made it possible for me to mount them! It took a bit for me to figure it out, but I'm grateful to have this guy!

It Works Like It Says

This tool is amazingly simple to use but it does take some muscle. The first time I used this on a really difficult-to-mount tire/rim, I was thinking "this tool is surely going to break" under the force needed to mount the tire... but it is built very well, didn't even flex and popped the tire on the rim. I've used it several times since and it makes this task so much easier. My thumbs are thankful!

I discovered this simple, elegant, effective tool after struggling way too many times to mount road bike tires. This makes it simple. I strap it to my second bottle cage, or store in jersey pocket when commuting and touring. Highly recommend.

This tool really helps with mounting 20 inch trike tires. I have no issues mounting larger tires on my bicycles but the 20 inch tires arent near as flexible. This tool isn't perfect but it does help get them on the rims.

I started installing my own tubeless tires this year. Because of the tight fit I struggled to get the last bit over the rim edge. With the Kool Stop Tire Bead Jack its like having an extra hand using the lever action to pull the tire up. I install gravel tires onto standard rims and Continental 5000 TL, onto my Bontrager XXX 4s. I use a combination of 2 plastic tire levers and the tire jack to get the last bit.

Very Clever+ Useful

Many older vintage wheel owners will find this VERY useful. Most newer rims are less an issue, requiring only fingers/ or levers. BUT, I couldnt be rolling my new gatorskins on a set of matirx wheels without this tool. A+++

If you've EVER struggled with getting a tire on your rim this would have solved your problem and saved your thumbs.

I broke 3 tire levers before breaking down and buying this item. The difference is unbelievable!

In my case I was using Vittoria Randonneur tires on a bontrager rim. I know some tires are very easy to fit on the same rims but I don't have those and had gotten quite used to the tires I had. I had also struggled before with the same tire but got over it. I didn't know there was such a gadget.

While not the smallest item its not too big to strap under your saddle. I won't leave home without it cos changing a tire in the rain is no fun. Changing in the searing heat is no fun. Now I don't worry about it.

Best tool for tight tires

It took three 60+yr old women to put on an impossibly tight new schwalbe tire (yes, even us oldsters still think we should be able to do this without paying a shop). This tool gave this little old lady the ability to change her own tire.

Mounted tries for over 40 year, but jut could not get this tire on. Thought I would try this tool. It's not perfect. However to be fair int might have been operator error. This was a particularly tight bead on a vintage rim. Tool kept slipping off bead as I struggled with the last six inches, but only if i tried to lift too much bead over trim wall at one time. Going inch by inch it worked although the bead itself kept crawling off opposite where I was lifting on. Fixed that by jamming another tire lever in to stop the bead from coming off. Glad to have it in the toolbox.

A must-have tool for every cyclist

Bought the Kool Stop Tire Bead Jack to assist in mounting a tight Veloflex Corsa open clincher on a Mavic Open 4 CD rim. I got both Corsa tires on with bare hands (see Veloflex review elsewhere, great tire!), but when I developed a slow leak in one tube, I decided to give my sore thumbs a break and take a chance with the Kool Stop tool. (Veloflex warns against using tools to mount their tight clinchers.) I am glad I did.

The Kool Stop is simple, strong and well made, and somewhat mimics the action of two strong thumbs. Best of all, it is safe to the tube, the tire, the rim and the user, yet enables one to slip the tire on within seconds. There's almost no way one could damage a tire or tube with the Kool Stop. Even if it sits in the tool box for months, the first time you use it, it will pay for itself, particularly when mounting, tight, flat, non-vulcanized high-threadcount tires like Veloflex or Vittoria. I would give it more stars if I could. Consider it like buying insurance. Hopefully, you will never need it...but you will be glad it is there if you do.

With 2-way fit rims, I always struggled to install new tires. Occasionally, I would pinch the new tube and have to remove and reinstall the tire. Since I got the Kool Stop Tire Bead Jack I have not had any problems - installation is now relatively easy. One of my best purchases.

Works well but be careful on rim edges
by David

I used these to mount a tough Schwable G-OneHED rim combination and ended up bending the bead of the rim. They work well but can provide too much leverage and damage your rim.

While I was never able to mount the Schwable on the rim, I removed them, straightened the rim flange, and was able to mount a similarly difficult Gravelking on the rim, this time being careful to not damage the rim flange.

So heads up.

Some of the newer tubeless tires are getting hard to mount, this lever helps pull that last section onto the rim.
