Kool Stop Tire Bead Jack, Black

This review is mostly for the company, but also for the product.While attempting to mount an extremely difficult wheel entire combination, I exhausted every tool in my shop. Three Pedro‘s levers, Park tool levers, and cheap levers that come with the tube, and I could not get the bead to seat. I ordered this Kool Stop Bead Jack after watching several positive reviews on YouTube. It broke while trying to seat the second bead, but I’m now convinced it never would’ve worked with any tool out there. By the way, I also had a Tyre Glider on the rim at the same time. Still wouldn’t budge.The wheel/tire combo was a Specialized Purgatory 29x2.6”, and the rim was a Ryde Trace 29er x 29mm.Now, here’s why this review is mostly about the company…I started down the road of the Amazon return process, but I realized two things. Firstly, the fact that I broke the lever while using it as intended is not Amazon‘s fault. Secondly, I would still like to believe that some US companies still desire to provide the kind of excellent customer service we all miss. I phoned their number, and two rings later I was speaking directly to a human. He introduced himself: “Kool Stop, this is Tim,” which is also my first name. He said “What’s up?” I briefly explained that it broke on the first tire, and without hesitation he asked for my address. He said “I’ll have another one to you today. If I can have your email address, I’ll send you tracking info, if you want.” The tracking information showed up a couple hours later.Ladies and gentlemen, this is a company I will enjoy doing business with for the rest of my life.By the way, I’m ordering new tires. The Specialized Purgatory 29x2.6” just won’t work with the Ryde Trace 29 rim. 🤷‍♂️

works great! The only way I could get Continental 5000 GP on my Campagnolo rims.I have been biking for a very long time, normally I just use my hands to get tires on rims. The continental 5000 gp are tight in general and my Campagnolo rims I think run large. I spent 2 days fighting the tires until I got this tool.

Worth every penny. I could not install a set of Marathon Plus tires on my rims until I got this tool. I used the tool and one or two zip ties (to prevent the tire from slipping off one end while I installed the other end) and was able to install the tires in a matter of minutes.

I was at my wit’s end - trying to R&R a set of tubes and tires…on my friend’s old Trek 1200 with Matrix wheels, (the original wheels that had been on his bike - hangin’ in his garage for over 10 years).The Trek1200’s were fantastic bicycles - but they had 700x20mm Matrix wheels on the rear, and 700x23mm rims on the front.I needed to replace BOTH - F&R - tires & tubes.The shortened story is this: I went with 700x23 tires on both F&R rims - stuffing butyl 700x20/25 tubes inside.I First broke a set of average (“cheezy”) spoons. So I purchased 2 more sets that were far better - but found that I was still unable to complete the job.I had almost got finished, - but in the process I had unknowingly “pinched” a total of 2 new tubes in my efforts along the way - making the job that much more stressful (and still unsuccessful).Then I saw this tool here on Amazon. After reading the reviews, (and being a bit In desperation) I ordered it.At that point, I had the second new tube installed on the front wheel - and with the first side of the tire bead completely on - only the last 6” of the final bead needed to be seated.THIS TOOL quickly made it possible to pull the tire bead over the rim edge and seat it correctly without damaging (or pinching) the tube.I was so relieved- but also knew that the rear “Matrix” rim was to be more of a challenge - being only spec’d @20mm (vs the 23mm width of the front rim).I had used cable ties to secure the tire to the rim at numerous places around the circumference - to hold the tire bead in its proper prospective & position (folded tires are a PITA sometimes) while I fitted it.On average tire spoons work great - but when things are this tight….. they “alone” are just not going to work.You can’t apply enough “stretch” in the tire runber, at the exact location it’s needed by simply “prying outward”.But this tool allows the “point of stretch” to be limited to the precise place on the rim - such that ALL of the stretch is advantageous to the area/direction needed - AND IS JUST ENOUGH TO place the bead properly - achieving proficient placement within the rim circumference - and just where you need it!As another reviewer put it, “Using this tool does not make this task “easy” - just possible”. That is totally HONEST!Thiis tool has not failed me yet. Changing out wider wheels like MTBs, or hybrids - you might not need anything but standard spoon levers to do the job.But for certain road bikes - particularly those with super skinnys on the rims - this tool is absolutely the champ. And you will be glad you had it in your box when the need arises.

I struggled to get the last few inches of my 700x25c road bike tire over the rim. Tire levers just wouldn't do the job. I had it done in about a minute after opening the Tire Bead Jack package. No slippage here. Saved my thumbs which were numb for hours.

Excellent product. Works as it should. Perfect device for mounting a new tire on a wheel.

With the new tubeless tires, mounting on rim can be difficult at best. I never go on a ride without this tool.
