Really you shouldn't have to use something this strong or something isn't right. Did try this on a Conti 5000 tl on a carbon rim with no luck. It will slip just like other lever tools eventually. I have seen people have great luck with this though so don't go by my experience.
Very helpful for installing tubeless tires that historically are a tight fit!
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 dint have those and had gotten quite used to the tires I had. I had also struggled before with the same tire but got over not. 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.
Purchased the tool and worked okay on one bike tire and broke on the other bike tire.
Makes tubeless tire setup very easy
Wire bead....ha! I laugh at you with my Kool Stop.
This tool is saving my thumbs and fingers. Getting a tire seated properly is easy. I should have bought one years ago.
good 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.
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
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.
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.
Used this tool to put on my Schwalbe Marathon 700c Tire (HS 420) 700x32 tires last night 8/21/20 and it made all the difference in the world .
I very highly recommend this tool.
Some of the newer tubeless tires are getting hard to mount, this lever helps pull that last section onto the rim.
