I’m half-fat with a 26 x 3.7″ Surly Larry tire up front and a 29 x 2.35 Schwalbe Big Apple in the rear. A 29 inch wheel is a great way to optimize a fatbike for summer singletrack, touring, or pavement. Half-fat is my half-baked idea of a bike that can go anywhere, but doesn’t ride like a tank. Half-fat: not half bad.
The simple and cheap option to refit a fatbike for general use is to select a high volume 26″ tire such as the Maxxis Hookworm 2.5 or Holy Roller 2.4; Schwalbe Big Apple or Fat Frank 2.35; and a host of other 2.3-2.4″ tires from WTB, Specialized, Kenda, and others. These tires mount nicely to a 65mm rim such as the Large Marge, but may be unworkable on anything wider. While the bottom bracket of the Pugsley is lowered over an inch, the height measures about the same as the Surly Long Haul Trucker and pedal strike is not a serious concern when cornering. For less than a hundred bucks, the bike is transformed with a fast rolling, durable, all around tire. The Maxxis Holy Roller 26 x 2.4 does the job on Lael’s Pugsley. Baby fat. Holy roller.
