Introduzione
With the many cranksets and bottom bracket types in the market, this guide specifically focuses on replacing a vision track crankset and similar Hollowtech II crankset. Since the vision track crankset does not have a square-tapered bottom bracket, different tools are required to remove and install the crankset. As the crankset is an important part of a bicycle's drivetrain, maintaining and keeping it in good shape is important. Before starting the guide, note that working on a bicycle is not very difficult but it can be messy.
