To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I was very disappointed to find that the one key piece of information I needed, how to adjust disc brakes that were rubbing, was not there. It is not a difficult procedure and easy to find online. Brakes rubbing is a common problem on bikes and one that often needs to be corrected so I would expect the procedures to be well covered in a book like this.
Beautiful graphics and diagrams - great as a basic guide, especially of learning to service a new bike, but not detailed or comprehensive enough for more advanced troubleshooting or repairs. Covers all types of bikes to some extent.
