At 80mm wide, the Big Aluminum Deal rim is an aluminum fat bike version of our carbon Big Deal that delivers similar benefits at a great price. Our engineers have delivered the same shape in aluminum to bring Big Deal technology to the masses. The aluminum rim provides superb fit with all common fat bike tire sizes. It features the patented Inflatobam tubeless technology, which its carbon brethren also have. This technology alone can save over a 500 per wheel in inner tubes or over 150g per wheel in rim and rim strip weight. The Big Aluminum Deal is available for immediate shipping, and can accommodate tire size options ranging from 3.8" to 5".
