It is no accident that Shimano is the industry leader in components. Their research and development team is relentless in creating products that are dependable, realistically light weight and above all function superbly under everyday riding conditions. Shimano cranks are second to none in the industry for durability and shift quality. As the old cliche goes; "imitated, never duplicated". To their credit, Shimano could have come out with a compact crank immediately during the height of Tyler's popularity but they waited until the shift quality met the incredibly high standards that their customers have come to expect. You can trust in Shimano's attention to detail they pour into all of their products.
