These hubs are the best quality and most durable we have tested, Bitex has a strong reputation in the industry for reliability. We also carry replacement freehub bodies and bearings for every model.  100% Nano Graphene allows us to build a very strong rim that is light and fast Moment of inertia: These rims being low profile will reduce the translational moment of inertia in simple terms the flywheel effect. This improves suspension response, acceleration, braking and cornering. Deep and wide tyre well for easy mounting of tubeless tyres.  Hookless rim, why hookless you might ask? Pacenti has always had its eyes fixed on the future, as stated in several independent articles in the cycling press: "What the bead hook doesn’t do is to prevent the tyre from blowing off the rim or keep tubeless tyres from burping". The bead lock and tyre construction are actually the main factors, our bead lock is secure and therefore we don't suffer burping even at lower pressures. We predict that bead hooks will all but disappear in the future.  Handbuild in the UK Parts manufactured in China, Designed in the UK.
