Hed B.D. Big Deal Carbon Rim - 85mm 26"



The Hed Big Deal Carbon Rim 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. 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. Hed's interior surfacing and tight tolerances ensure no tire burp or slip. Note that the Big Deal rim shape does not require tire levers to remove and install tires. Inner tubes may be used, too. Note that the Big Deal is drilled symmetrically ONLY and cannot accommodate offset frames.
