Giant Innova Crankset Replacement

Introduction

Owners of the Giant Innova bike may experience problems with the crankset after extended use. This bike was made in the early 90s, and some bikes still sport their original crankset. Over time, the crankset can develop rust and worn down teeth on its gears. A worn crankset can compromise your bike's performance and lead to issues such as a skipping chain. Replacing your crankset will lead to more fluid pedaling and gear shifting. This guide could be useful if you are attempting to replace a crankset on a similar bike such as another 90s roadbike; however, there are many different types of cranksets, so this is not a universal guide.
