Designed for ease of use, comfort, and lasting durability, Pedro's professional-grade 2-Piece Screwdriver Set provides the common sizes found on bicycles. This includes a #2 Phillips and a 5. 5mm flat-blade screwdriver, both featuring dual-density, ergonomic thermoplastic handles to provide a comfortable grip and plenty of leverage. The screwdrivers are constructed from heat-treated tool steel for strength and durability, and they're backed by Pedro's lifetime warranty.
