Customizing a fatbike
Bruce Ingle customizes a fatbike —

Our new article will help you to customize a fatbike, but also gives you a look into customizing bicycles, in general.
The article is taken from a running e-mail discussion in which Bruce contemplates choices, decides on a bicycle purchase, and describes the various steps of customization and how they worked out.
