This hub represents a total redesign over the original TT unit and features a very high quality German one-way clutch bearing that incorporates twin needle roller support bearings in place of the plain bushes used by TT.
A new 18mm hardened steel core allows the use of the larger clutch bearing giving a 30% increase in torque handling. The hub body now fits to the top face of the maingear allowing for increased wall thickness and rigidity whilst a separate reinforcing ring attaches to the gear underside to prevent distortion.
Despite the increased proportions of this unit we have actually engineered a 7% reduction in weight compared to the standard TT unit with the steel reinforcing ring !
Supplied with full fitting instructions and compatible with all types of maingear options and available in Cool Blue or Satin Silver finish.
