Oregon® Rims
Rims provide the ultimate cutting system performance.
• Smoother cutting and less chain wear than spur sprockets • Radial port design uses centrifugal force to throw off sawdust and debris • Wear-depth indicators show when it’s time to replace the rim • Replacement schedule: every two chain loops
