The supplied aggregate ratings are positive, but the sample is very small and there is no written customer feedback to explain the scores. They cannot establish how shifting performance or durability will be for a particular bike. Fit the stated cable and housing lengths to your routing needs, and treat the claimed coating and grease benefits as manufacturer descriptions.
