This TOOPRE M20 crank cover cap is a high-quality, lightweight bicycle spare part designed for hollow-spindle cranksets (such as Shimano XT). Precision-machined from aluminum alloy using CNC turning and an anodized finish, it offers excellent durability and a vibrant aesthetic. The cap features an M20*8 specification with a specialized Torx-style interface, requiring a dedicated plum crank cover tool for installation. Weighing only 3.9g, it is an ideal upgrade for road, mountain, and urban bikes, providing both protection for the crank spindle and a clean, professional look. Each unit comes in a branded, resealable zip-lock bag for easy storage.
