Industry Nine Grade 300 V2 Wheelset

Yes, the Grade 300 V2 wheelset is officially approved for Class 1 e-bike use. The robust construction is specifically engineered to handle the added weight and torque of modern electric mountain bikes.

The hollow bead wall design acts as a buffer against hard impacts, significantly reducing the likelihood of pinch flats. It provides extra structural integrity where the tire meets the rim, which is crucial for aggressive downhill and bike park riding.

The Hydra freehub features 0.52-degree engagement, which translates to near-instant power transfer. You will notice this most on technical climbs or when you need to ratchet your pedals through rocky sections, as there is virtually no dead space in the drivetrain.

This specific wheelset is built with a Shimano Micro Spline freehub body. You will need a drivetrain compatible with the Micro Spline standard, such as Shimano 12-speed systems.

The direct-thread aluminum spokes create a very stiff, responsive wheel, but they do require specific tools and knowledge for truing or replacement. While they are highly reliable, you should be comfortable with or have access to a shop familiar with Industry Nine's proprietary spoke system.

The 30mm internal width is the industry standard for modern trail and enduro tires. It pairs perfectly with tires ranging from 2.3 to 2.6 inches, providing a stable, square profile that resists tire roll during hard cornering.
