BBI releases 12th edition of Barnett's Manual DX

Published December 1, 2017

COLORADO SPRINGS, Colo. (BRAIN) — The 12th edition of Barnett Bicycle Institute's Manual DX is a 600-page update to the existing manual, bringing the total manual size to 14,000 pages.

The 12th edition update includes new sections on Shimano's Di2 mountain bike components, including 1x, 2x, and 3x drivetrains; Fox spring and damper upgrades; and SRAM 1x11 and 1x12 drivetrains. 

John Barnett created the manual with the goals to write the clearest measurable procedures, to ensure repeatable results, and to help raise the bar on quality of service. 

"As the author, it has been my life's work and my personal obsession to create the ultimate reference manual for the professional bicycle mechanic," John Barnett said. "Having a copy of DX at your workbench is the closest thing there can be to having a portal directly into the bike-technology part of my brain. Come on in, I guarantee you'll find more than you can ever have imagined about the amazing subject of bike technology."

Each procedure in the manual includes a careful arrangement of written steps, photographs, and hyperlink functionality.

Barnett's Manual DX is available for purchase online at or by calling the institute at 719-632-5173.
