The hex wrench is the most common tool needed for the modern bicycle. Choosing the right set can make the difference between good day and a bad day working on bikes. Pedro's L Hex Wrench Set is up to the challenge. We made these wrenches from heat-treated SNCM-V alloy steel to ensure superior strength and lasting performance. Pedro's hex wrenches also feature extra length and a round-style end for better leverage and easy access and handling of hard-to-reach bolts.
