About LezyneLezyne was founded on March 1st, 2007, by industry icon (and German native) Micki Kozuschek. At a time when poorly engineered, plastic catalog-copied accessories were the standard, Lezyne's goal was to engineer and produce premium quality accessories that meet the same high standards as high-end bicycle components. In few words, Lezyne's goal was Engineered Design. Today, the goal remains the same and Lezyne is now a cycling accessories industry leader with award winning products worldwide. Innovative products like the CNC Floor Drive with its secure ABS chuck connection, the Carbon Road Drive with light-weight Full Carbon Technology, and multi tools using Center-Pivot bit design set Lezyne apart and ahead of the competition.Lighting Buying Guide
