Why Cycles Big Iron V2 fat bike loads updated geometry plus SRAM UDH

It may be named after the famous Marty Robbins song, but the Why Cycles Big Iron isn’t actually iron. Instead, it’s a titanium fat bike designed to be the ideal tool to venture out for all kinds of fat bike adventures. And now, the Big Iron has been updated with a few frame tweaks to make V2 even better.

Like V1, the Big Iron V2 is intended for use with 27.5 x 4.4″ or 26 x 5″ fat bike wheels and tires. That includes adjustable dropouts which allow you to change the chainstay length from 445-460mm to keep the ride as snappy as possible with those gigantic tires.

Additionally, V2 includes a slightly longer reach and a taller stack height. Why claims that this increases the comfort and control of the original, resulting in a bike that handles better with low pressures up front. There’s also a lower seat tube and curved top tube for improved standover—which becomes more important on smaller sizes with the super tall 27.5 fat bike tires.

As an added bonus, the rear dropout has been updated to be compatible with the SRAM UDH. With more and more companies adding the UDH to their bikes, we’re getting closer to realizing the potential of a truly universal derailleur hanger.
