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.
Gear Calculator updated and now also in German

Remembering Sheldon
“The bicycle on the cover was produced on the Management Graphics Table Top Slidemaking System at Crimson Camera Technical Sales in Boston. A bicycle enthusiast created the image using the tablet menu and cursor tracker. The bicycle is made up of 99 vectors, 20 circles, and 5 ellipses. This simple graphic was created to illustrate to customers what 4000-line resolution looks like.”
The “bicycle enthusiast” was Sheldon Brown who worked for a short time at Crimson Camera. Sheldon died eight years ago today.
