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.

Never ride without it

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.

Helps with mounting 20 inch recumbent trike tires

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.

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.

Awesome little tool

This makes life a little too easy. I almost miss the challenge of putting on tight fitting ties with my bare hands until my palms are blistered, then resorting to using tire levers and pinch-flatting a couple of tubes. Ha! Never again! I ride a touring bike with a giant seat pack and keep this with me all the time.

Extra leverage for mounting tires.

The Kool Stop Tire Bead Jack provides extra leverage for mounting those hard-to-mount tires. However, you must be careful not to pinch the tube when you grip the tire. It may be better for mounting tubeless tires. It works fine at home but it is too long for most seat bags or jersey pockets so it's not easy to take on the road.

Time and finger saver

After a 2hr. struggle with Schwalbe tires and Mercury carbon rims I gave up. Saw the bead jack and gave it a try. 5 min. to mount 2 tires. Hooks over bead and levers over rim edge. If using tubes avoids the dreaded tube pinch.. Makes the first mount of tight tubeless tires to tubeless rims fairly easy. One of the top tools I have ever purchased for making your mechanic life easier.

Great tool to install tires

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.

easy tire handling

It greatly helps to get the very tight fitting tires off the rims for more easily repairing flats on the road. The length makes it hard to store in most under saddle bags
