Shimano has implemented the perfect balance between weight, power-transfer, efficiency, stiffness and comfort with the R7000 chainset while keeping it at a price that is ideal for riders on a budget; leaving more cash for mid-ride coffee breaks. This chainset has been designed and refined to ensure maximum levels of power-transfer from rider to road are maintained. Thanks to modern technology, Shimano has designed this crankset with the perfect gear-pitch so it performs exceptionally with standard road frames (130mm rear dropout spacing) and modern disc brake frames, which have a wider 135mm dropout spacing and wider chainline. This design pushes the advancements of road chainset performance and achieves exceptional levels of efficiency and comfort.
