Dirt Tricks Zirconium Rear Sprocket 51 Tooth Diamond Gunmetal Black BT-51 D-B
Details
The Zirconium Rear Sprockets are part of Dirt Tricks' latest sprocket design and are a revolutionary change from traditional sprockets in both weight and color. Dirt Tricks Zirconium Sprockets are extremely lightweight compared to all other twin-ring designs—aluminum on the inside and steel on the outside—and have six times the lifespan of most aluminum sprockets. The new zirconium coating on these sprockets reduces friction up to 50%, gives your bike a trick look, and increases durability so much that Dirt Tricks offers a 2-year wear warranty.

Lasts six times longer than most aluminum sprockets.

Machined to the tightest industry standards and tolerances.
