Description

The Engineers here at Dirt Tricks are so happy to finally launch some of the lightest and strongest 520 conversion sprockets on the market. Made from a special proprietary steel rather than aluminum or stainless makes these rear sprockets at least 3x stronger than other units out there and longer-lasting nearly 3:1 on average. Machined with the tightest industry standards and tolerances. Zirconium plated and laser-etched designs allows us to offer a 2-year wear guarantee, with a free replacement due to defects in materials, craftsmanship, and excessive wear.
