New wide link design is lighter, more rigid and durable. The increased rigidity stabilizes the chain as it glides up and down the sprockets. Less play means rea shifting is not only quicker, more precise and reliable, but it also insures better indexing over many more road miles.
Combined with the new SP41 silicon grease injected cable housing, RD-7800 adds key advantages: lighter weight and crisp, instantaneous shifts that are 10% more efficient from lever to RD.
