Bikes. Parts. Chaos.

My Other Brother Darryl is a single-wall, 80mm-wide fat bike rim. 80mm-wide rims give you a bigger footprint than narrower rims. That means more floatation and more traction. To initiate tubeless sequence, you just need a no-stretch rim strip and bead-to-bead tubeless rim tape. My Other Brother Darryl comes with either a 32-hole, symmetric wheel lacing spoke hole pattern or our tried-and-true 64 dual spoke hole pattern, which allows for symmetric or offset wheel builds. It’s got plenty of cutouts to keep the weight down and help your tires float through the squishiest of terrain.
