Big Fat Dummy is truly a hulking beast of a bike. Maximalist bikepackers, those looking to make bikepacking a family affair, and those that help maintain their local trails will appreciate the Big Fat Dummy hauling abilities.
At first glance, it might just seem like a beefed-up version of Big Dummy, but that’s actually not the case. Specifically designed around fat tires, it has a longer toptube and slacker headtube offering the most stable, stiff, and predictable ride possible while hauling a lot of cargo.
Single-piece frame increases stiffness and decreases torsional flex
Human cargo compliant with the use of Dummy Rail Collars
Three-pack mounts, double water bottle bosses on seattube, internal dropper post routing
Clearance for 26" x 5.25" tires or 29” x 3.0” tires
