Built around the new standard 27.5” fat bike wheels with clearance for up to 27.5×4.5” or 26×5” tires, this modern titanium steed will be your trusty companion on any snow or soft-surface endeavor. The crew at Why goes way back to the early days of fat biking in Alaska, and the Big Iron is the culmination of years of fat biking experience combined with modern design features, and an engineering oversight to optimise Why’s titanium tubing to the rigorous riding the Big Iron is made for.
 
Named after the the famous Marty Robbins song, the Big Iron is designed to be a tool to get the job done. Whether its a short weekend jaunt on the local groomed single track or an epic 1100 mile journey across Alaska, the modern geometry, stiff-yet-supple titanium frame, and lifetime warranty make this a bike you’ll be proud to take anywhere that requires big tires.  Would you like to see some custom built Big Irons?

Geometry

The Big Iron uses truly modern mountain bike geometry adapted for use with super-huge 27.5 fat bike tires. The reach is longer than most other fat bikes, which allows for the same body position using a wider bar and short stem. The handling benefits of this setup are magnified in snow riding with a sometimes unstable front tire at low pressures. The chain stays are adjustable from 445mm to 460mm so you can really dial in the rear-end snappiness of this bike based on the tire size you choose. A lower seat tube and curved top tube allow for excellent standover height while allowing for the use of a longer than normal dropper seatpost, and still keep a nice big front triangle if you choose to use a frame bag for gear storage.

 

Because titanium is magic
We make our bikes form the best materials possible for the terrain we ride. For now, that means titanium, but we’re not stopping there stay posted. We use the highest quality Grade 9 3/2.5 titanium for our frames’ tubing, and 6/4 titanium for the head tube, bottom bracket shell, and machined bits all over the frame. The wonder material has so many excellent ride quality attributes: 43% lighter than steel, higher strength-weight ratio than aluminium, significantly more resistant to crash-damage than carbon, and the best vibration damping properties of all three listed here. We think you’ll agree that we achieved our goal of creating titanium frames with a modern twist by engineering guided internal cable routing, stealth dropper post routing, integrated headsets, and threaded bottom brackets. For riders who want a high-end, comfortable, fast bike built to last a lifetime, we believe a properly made titanium frame is the best option.
