Lezyne CRV tools are functional, lightweight, and durable tools ideal for roadside or trail-side use. The forged aluminum side plates are lightweight and easy to use while wearing gloves. The chrome vanadium bits and fastening hardware are nickel plated. Forged Center-Pivot bits increase tool rigidity and improve ergonomics.
