HED Big Deal Carbon Fat Rim Big Deal is 445 grams and 85mm-wide of pure fat-bike joy. This one-piece, full-carbon 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. Compared to most aluminum fat bike wheel/tire combinations in the market today, you can expect to lose 1.5 to 2 pounds… per wheel. Note that the Big Deal is drilled symmetrically ONLY and cannot accommodate offset frames. Big Deal utilizes Inflat-o-bam, 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, Inflat-o-bam utilizes Inflat-o-bands. 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. Also note that our rim shape does not require tire levers to remove and install tires. Inner tubes may be used, too.
