The Nukeproof Generator 650b factory wheelset delivers all the performance attributes of the Generator family of wheels in a larger-diameter hoop. Suitable for technical XC, Trail and All-Mountain riding.
Featuring 32-hole Nukeproof Generator hubs cold-forged from 7075-series aluminium and plain-gauge DT Swiss spokes.
Nukeproof Generator hubs are essential components for any high-grade wheelset, providing smooth and long-lasting bearing performance, a light weight that belies their ability to take hard knocks and enough axle options to satisfy every riding discipline and every rider.
The new Generator rear 135mm multi-axle rear hub features an interchangeable axle system allowing one hub body to be used with multiple axle sizes including QR, 12mm and 142mm without the need to remove bearings.
A tough but lightweight 7075-series aluminium main hub body features cold- forged construction for optimum strength and fatigue resistance while extensive CNC machining shaves excess weight without compromising structural integrity.
The hub features a total of five sealed cartridge bearings (six on 150mm version): two on the drive side to help spread the loads of pedalling forces through the hub, one on the non-drive side and a further two in the freehub body.
A low friction seal between the bearings and freehub body eliminates contamination of the bearings from ingress of water and dust.
Six pawls with leaf springs are located in the main hub body for ease of maintenance and engage into a 30-tooth steel ratchet in the alloy freehub body for additional strength and increased leverage ratio, which provides positive engagement and super fast pick up for increased acceleration.
The alloy cassette carrier (steel on short-cassette option) has been cold forged with extensive CNC machining to exacting tolerances and features a hard anodized finish for durability and strength.
The Generator 650b rim is based on the proven Sun Ringlé Inferno rims, the 32-hole Generator is welded for strength and features a 27mm rim width for trail and technical XC.
