Whether we are racing or just a weekend warrior, when we want to improve our performance on the bike, having a quality set of carbon rims usually does the trick. The Industry Nine EN325/310 29in Carbon Super Boost Wheelset are top-tier enduro wheels designed for aggressive enduro riding and racing. These rims have a front and rear-specific design with an internal diameter of 31mm to 32. 5mm. The carbon fiber layup is specific to each rim, with the front being wider and more compliant, while the rear is stronger to absorb bigger impacts. To top it off, Industry Nine threw in their Hydra hub to give us a premium hub that has some of the fastest engagement out there.
