At DMG Motorsports, we present the RK Excel 520XRE Drive Chain (520 X 150, part 520XRE-150) — a lightweight, high-performance chain engineered for riders who demand durability without sacrificing quick, smooth acceleration. As the successor to RK's popular XSO line, the XRE series was built with RK's original double-X-shaped XW-Ring seal technology, giving this chain exceptional wear-life and reliable performance whether you're carving up pavement or tearing through the dirt.
