Product Details

This is the Performance Machine 21 x 3.5 inch Assault forged front wheel in a Black Anodized finish. It's built for riders who want a strong, lightweight wheel that can handle high performance riding. The Assault wheel uses an 11-spoke design that looks sharp and contributes to its overall agility.

What really sets this wheel apart is how Performance Machine works to reduce weight. The rim lip is back-cut, which shaves off mass from the outer edges. This not only makes the wheel lighter but also decreases rotational inertia, meaning it spins up and changes direction more easily. It's also equipped with Performance Machine's Raceline Series hubs, which have had all unnecessary material machined away to further reduce weight and unsprung mass. This attention to detail means you get a wheel that's not just about looks, but also about improving your bike's handling and responsiveness.

This wheel is designed for non-ABS applications. When installing, remember that reducing unsprung weight can have a notable impact on how your bike feels and handles, especially during spirited riding or braking. It's a solid option if you're looking to upgrade your bike's performance and aesthetics with a well-built, lightweight forged wheel.
