***Video Reviews***

Most aluminum rear sprockets start out as blank discs punched out of sheets of heat-treated 7075-T6 aluminum. The quality of these aluminum sheets vary among manufacturers and countries. DRIVEN uses only the finest aluminum available in the world. They shape the tooth profile on a hobbing machine, which guarantees the perfect shape and fit for the least amount of friction and subsequent wear when mated to the chain. The final color anodizing further increases strength and durability as well as adding a personalized characteristic. Throughout the entire process the disc undergoes rigorous quality control insuring each individual sprocket is perfectly flat and concentric. This guarantees the consumer the finest product available. Their front sprockets are made of case hardened, C45 chromoly steel, zinc plated for strength and durability and drilled for mass and weight reduction.

For most 600cc bikes we suggest 1 down in the front and 2 up in the rear. For most 1000cc bikes we suggest 2 up in the rear with a stock front. This may not be correct for your intended application. If you need assistance with choosing the sprocket combo contact us prior to purchase as we are happy to help.

Note: Certain color combinations are special order and may have longer delivery times than standard color combinations.
