CRG (Constructors Racing Group) is the manufacturer of the original One-Finger-Adjustment Roll-a-Click lever that every other lever maker has attempted to replicate since its introduction. Offering true on-the-fly adjustability, CRG levers allow riders to manipulate lever positioning while riding.

CRG Levers created a major change in the world of sportbike controls when their roll-a-click levers were first introduced. At this point, you can get levers for almost every street bike on the market, in an array of colors and lengths. CRG manufactures all of their components in-house employing CNC, or Computer Numerically Controlled, production processes. They exclusively use solid aluminum billets, precision ball-bearing pivots, and stainless hardware. Their commitment to quality is evident in all of their products, and they are advocated by World Superbike and AMA championship winners.
