Customizing a fatbike
Bruce Ingle customizes a fatbike —
Fatbikes are intended for use on soft, muddy, sandy, snowy surfaces but they need customization to make them truly practical for such use — in particular, fenders, wide-range gearing including ultra-low gears, and a way to carry baggage. 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.

Revisions to the Shimano Rollerbrake page: links to Shimano’s (finally) well-organized compilation of Rollerbrake documentation; information on installing front Rollerbrakes.
