Product Description

NINETEEN BOOST Rear wheel hub

As a subsidiary of a rolling bearing manufacturer, Acros has developed a completely new bearing. This newly developed stainless steel angular contact ball bearing was uncompromisingly adapted to the intended use - in short, weight down, load up.

In all NINETEEN hubs 19 mm King-Size aluminium axles are used. This makes the hubs unbeatably light and at the same time more rigid. Furthermore, the new freewheel system was changed from handles to a ratchet system. The hub body is made of 7075 aluminium and, depending on the hub model, has a straightpull or normal flange to achieve the optimum wheel stiffness for every application.


  • The Clamp System - Play in axial direction can be adjusted
  • traightpull flange - for maximum wheel rigidity
  • Ratchet system - Increased service life and better power transmission
  • 19 mm aluminium axle - even lighter and stiffer
  • R2 (rubber lip seal), R3 (metal-supported rubber seal)
