In the varied and ever-changing garden of bicycles, it seems that the fat bike corner is the latest area of flourishing growth, producing new ideas and iterations at a rapid pace. Two longtime mountain bike innovators—Aaron Joppe, former owner of Slingshot, and John Muenzenmeyer, former owner of Nukeproof—have been drawn into this bloom and are making interesting contributions with their relatively new company, 616 Fabrication.
The company name comes from the area code of western Michigan where they manufacture frames, forks and hubs at their own facility. They offer frames for fat bike, cyclocross and mountain builds, all made in high-end steel. Artistic touches, such as laser-cut seatstay bridges and custom-etched ID plates, further set these creations apart from the average mass-produced models, as does a classic paint job.
The first thing I and other staffers noticed about the Fat frame is its relatively steep 72 head tube angle. It also sports short-for-a-fat-bike 17.5-inch chainstays. Hub spacing is 135mm front and 170mm rear. It’s designed to ride light and nimbly over sand, snow and rock. Custom geometry is available to suit anyone’s taste, but for our tight turns and four seasons, the stock numbers suited me just fine.Tweet Print
