LIGHTENING HOLES.
Featured on many of EK’s racing chains are lightening holes. Here specialised manufacturing allows EK to add holes to each side plate, resulting in a total weight saving of 3% without sacrificing any tensile strength. These lightening holes also extend chain life by dissipating heat and deterring mud build up.
