Ronstan ball bearing Orbit Blocks boast the highest strength-to-weight ratio available. This is achieved through all-composite reinforced polymer materials and multiple attachment options. Their precision design provides the optimum number of ball bearings for minimum friction while weight reduction is achieved through the use of fibre-reinforced composites in the block head, cleat arms and beckets. This link block configuration features two 30 mm single blocks with UV stabilised, multi-strand impregnated SK75 Dyneema link.
