In ancient Greek mythology, the Chimera was a hybrid creature that was part lion, part goat, and part snake. It’s also the name of our expedition ready fat bike. When we set out to make a fat bike, we wanted something we could ride all year round. The Chimera has a stable and buoyant ride on snow while also being an extremely capable trail shredder. With a full compliment of rack braze-ons and triple bottle mounts, loading up for a week of touring in the desert is no problem. Sliding dropouts make running singlespeed a breeze while also giving you the option of changing your chainstay length. And like all our frames, it’s proudly made right here in Durango, Colorado.

Thermlx logoPMW logoThe Chimera is built with Vari-Wall seamless tubing. Vari-Wall has been manufacturing bike frame tubes for more than 20 years out of their Columbiana, Ohio location. Their commitment to American manufacturing and high quality products make them a perfect source for our frame tubes. Most of the frame components such as dropouts and head tubes are sourced from another American manufacturer, Paragon Machine Works in Richmond, CA.

Crank Compatibility

One of the best features of the Chimera is it’s ability to run certain specific narrower Q-factor cranks and still have good chainline. Our favorite is the Raceface Aeffect crankset with a flipped Cinch chainring. This is a great option for smaller riders or anyone who doesn’t want the wider stance of cranks usually found on a 5in tire fat bike. All this is done with a 100mm bottom bracket, so you can also run the wider cranks if you want to. At Myth Cycles, we’re all about options.
