A good set of Allen keys is essential for every cyclist and Birzman’s Long Arm Hex Key set is worth considering.
There are 12 Allen keys here, covering sizes from 1.5 to 10mm, including less regular sizes such as 4.5 and 5.5mm. They’re made from Chrome Vandium steel and to the highest quality, making both durability and fit fantastic. The robust ball ended tips are extremely handy for those awkward to reach bolts too.
It’s a small detail, but the hard plastic holder has lasted well and pivots for easier access to the smaller keys. Although £25 might sound expensive, all the tools in this little number should last for years.
