As wide as it gets. As light as it gets. And that's a Big Deal. With a ready-for-whatever width of 85mm and an weight of 565g per rim, HED's Big Deal fat bike wheels might be the most fun set of wheels in the HED lineup. 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 Inflatobam, HED's patented tubeless technology 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.
