The HED Big Deal Carbon Rim is an impressive piece of engineering technology. Its rubbed, single wall design maximizes the stiffness while keeping the rotational weight as low as possible. When you break down the numbers the HED Big Deal Carbon rims can save you approximately 1.5 to 2 pounds for each wheel. The tubeless setup is a breeze when you used HED's spoke washers, and that does not even require the rim to be taped. If you want to push your fat bike to the limit, do so with the Big Deal Carbon rim from HED.
