Being an expert desert racer, Greg became tired of changing aluminum sprockets every two months. His goal was to create a sprocket that would last an entire season of hard riding, yet be comparable in weight to aluminum. Thus, the Dirt Tricks sprocket was born. It required two years of development and testing, but the end result has proven to be the toughest, most durable off-road sprocket available.\u003cbr\u003e\u003cbr\u003eDirtrick's Chrome Rear Sprockets are 2.5 times stronger than stainless steel and use a unique “minimalist” design and appearance. \u003cstrong\u003eThey back these sprockets with a one year guarantee: if you wear it out, they will replace it.\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eBlack and Chromatic Rear Sprockets use their latest design and are a revolutionary change in weight and color. The new Dirt Tricks Zirconium Rear Sprockets are 2oz lighter than the chrome plated design, and are comparable to most of the performance aluminum sprockets and lighter than the twin metal designs available.\u003c\/p\u003e \u003cp\u003eThe new coating on these sprockets reduces friction up to 50%, increases durability, and looks sharp! These sprockets will outlast any sprocket on the market, and we back that up with our 2 year guarantee.
