Founded in Osaka in 1916, IZUMI (officially Izumi Chain Mfg. Co., Ltd.) is a comprehensive chain manufacturer.
For over 100 years, this long-established company has continued to produce various chains, not only for bicycles but also for industrial machinery and motorcycles.
Long used in the world of Keirin, IZUMI chains—certified by the Nihon Jitensha Shinkokai (NJS)—are known for their high precision and durability.
Among track bike enthusiasts, the image of "chains = Izumi" is well-established.
Now, a collaboration between Izumi Chain and RUNWELL, a brand known for its specialized track bike tools, has resulted in the world's first portable tool exclusively for connecting NJS-certified chains!
A Professional Tool in a Compact Size
IZUMI Fixer
Color: Black / Silver / Gold
Material: Chrome molybdenum steel
Weight: 51g, Length: 40mm
Price: 3,949 JPY (tax included)
So compact it looks like a mere keychain at first glance, this tool is actually a reliable companion for connecting your chain.
The keychain-style design makes it easy to carry and store, taking up no space in your garage or at cycling events, allowing you to pull it out at a moment's notice.
While simple in appearance, it disassembles into a small screwdriver and a pair of pliers. These serve as the dedicated tools for tightening the small bolts and plate nuts that come with track bike chains.
The small groove features a powerful magnet that holds the tiny nuts you've removed, allowing you to work without the worry of dropping them on the floor and losing them.
This is a small but professional-grade tool that fuses the precision technology of long-time chain maker Izumi with the design expertise of track bike tool brand RUNWELL.
Speaking of compact…
BLACKBURN Big Switch Multi Tool
Size: Width 140mm x Height 135mm x Thickness 20mm
Weight: 120g
Price: 5,500 JPY (tax included)
While not an Izumi Chain product, this portable tool is also remarkably compact yet features 15 functions.
It includes Torx keys, hex keys, a flathead screwdriver, spoke wrenches, and even a disc pad spreader. With this much included, you could say it’s the near-perfect kit for handling on-the-road repairs.
The mesh pocket inside the pouch is perfect for storing repair patches, but you can also tuck away your ID, credit cards, or even some emergency cash for peace of mind.
And to top it off, it comes at a very wallet-friendly price for the number of functions it offers!
A Reliable Little Partner on the Road
Whether you’re in the city or on the trails, being prepared with tools is essential.
No matter how well your bike is running, unexpected trouble can always happen while you're out. Having a palm-sized tool can help you handle things calmly, whether it's a loose chain or a slightly misaligned bolt.
Rather than just "fixing," having the peace of mind that you can handle things yourself makes the ride itself much more enjoyable.
Tucked into a corner of your bag, these reliable little tools can turn even a minor mishap into part of the fun, whether you're commuting on a track bike or off on a trail adventure!
