The N3W freehub was created to host cassettes starting with 9 and 10 sprocket but it opens us a wide range of future opportunities. At the moment we are focused on disc brake developments so only our disc brake future wheels will be updated to this standard. Our Campagnolo rim brake wheels will continue to use the classic Campagnolo freehub. We cannot guarantee the same for third party wheels so, in case you will buy another brand's rim brake wheel with the N3W freehub and intend to use it on a Campagnolo rim brake drivetrain remember to purchase the AC21-N3W adapter because all our rim brake drivetrains have cassettes that start with 11/12 sprocket.
