The Big Deal is 445 grams of pure fat-bike joy. This one-piece, full-carbon constructed rim will change the way you ride. Big Deal utilizes a ribbed, single-wall design to maximize stiffness and minimize rotational weight…all on a tubeless ready platform. Expect your fat bike to lose between 1.5 and 2 lbs per wheel! The 85mm rim does not require tire levers to get tires on or off.
Big Deal utilizes Inflatobam, Hed’s patent pending tubeless system for installing big tires. The twin channel rim design provides a better pre-inflation seal by trapping each tire bead against the rim. This drastically reduces the amount of air it takes to get the beads to “bam” into place. In conjunction with the rim shape, Inflatobam utilizes Inflatobands. These effectively provide a variable rim-channel diameter. This compensates for the discrepancies in tire bead diameters by minimizing the gap between the tire and the rim channels (the main source of air leaks). Once seated, the angled bead shelf prevents the tire from collapsing back into the rim at low pressure. Our interior surfacing and tight tolerances ensure no tire burp or slip. Welcome to a new era – consider yourself Inflatobammed!
