Park's Hex Wrench Set offers all the popular Allen wrenches (1.5, 2, 2.5, 3, 4, 5 and 6mm) in a convenient fold-up unit. The tool tips are chamfered for a positive grip and the one-piece fiber-reinforced-resin handle is light, comfortable, slip resistant and 40% stronger than steel.
You need allen/hex wrenches wherever you go. you might need to adjust components etc. this tool does not rust easily and has plenty leverage. i have used this tool countless times and all the sizes you need are in this tool. this can also fit in your pouch or bag. the only cons is that the tools get loose easily so i need another tool to tighten them every now and again. it also feels like your going to snap the plastic body but hasn't snapped yet.
Bottom LineYes, I would recommend this to a friend
