Why Cycles Big Iron V2 Titanium Fat Bike

The Big Iron is 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 optimize 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.

BECAUSE TITANIUM IS MAGIC

Why Cycles makes their bikes from the best materials possible for a wide variety of terrain. They use the highest quality Grade 9 3/2.5 titanium for their 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 aluminum, 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 they achieved their 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.

*Builds are subject to slight changes based on availability. Customers will be notified

How our Builds Differ from the Stock Why Cycle’s Build:

  •  We start with the industry’s most reliable high engagement wheelset; The Corvus Big SU! The Big Su’s highlights are the high engagement 6 pawl hubs designed for AK durability laced to thier own ultralight (540g) 80mm rims. We also offer the HED BHAD wheelset which is the lightest aluminum wheel on the market! The stock Why Cycle’s build offers the Sun Ringle Mule Fut which is a heavier and less reliable entry level wheelset.
  • Why Cycles uses a Bontrager Fork. We use a higer quality Enve Fork! Or the Manitou Mastodon Pro (2024 version) Suspension Fork!
  •  To go along with the long standing durability of the Why Cycles Ti frame, we have
    assembled components that match that reliability and quality versus the stock build
  •  Like with most models that we carry we offer multiple tire options; both studdable and non-studdable

Other Build Options:

  • Higher end drivetrains and components potentially available upon request!
  • Total custom builds also available to create your ultimate dream machine. This can include coloured ONYX hubs, coloured wolf tooth bling kits, plus more!
