NS Bikes Rotary Rear Singlespeed Pro Hub

The Rotary is a real street/dirt mountain bike disc brake SS hub (135/10) using pure bmx technology. Say no to the heavy hubs taken straight from bmx catalogues with tiny & weak driver bearings & weak 3/8" axles. The Rotary hub is so light because we decided to shave any unnecessary weight to the limit without sacrificing the strength at all.

Instead of a long and weak 3/8” axle we used a bigger diameter alloy 7075 axle & steel hardware on the drive side to make it almost indestructible. No more adjusting, no more unscrewing or stripped cone nuts - they are slip-on. No external threads to damage. Hollow 3/8” bolts with 17mm hex heads & 8mm Allen hex sockets will fully immobilize your wheel in the dropouts. The driver runs on a bushing eliminating the need to use tiny and week bearings. It’s strong as hell and run smooth. Engagement is really good – this hub won’t skip.
