I’ve been using the Kool Stop bicycle tire jack ever since I first learned about it when I was cycling across the United States, see Day 35 – Silsbee, TX to De Ridder, LA – Cycle Across America. It is a fantastic tool for mounting tight fitting bicycle tires. While I would still highly recommend the Kool Stop as a great compact tool to stuff in a seat bag for quick puncture repair when touring, in my home shop I’ve switched to a generic plier-like tire jack pictured below.
The plier-like tire jack makes grabbing the tire bead and rim a faster and easier one-handed operation. However, although the plier-type jack is easier to use, I don’t think I would ever carry this bulky tool in a seat bag for emergency tire repairs. Nevertheless, I found it easier to use while servicing my tires in my home shop.
If you struggle with mounting bicycle tires like I do, I highly recommend the Kool-Stop Tire Bead Jack or the generic plier-like tire jack. Pick one or both up at your local bike shop. If your local bike shop doesn’t have them (many bike shops don’t), they can easily be found online.
