The front hub CRG 17 mm in size m (Medium) is a high-end frame of the original manufacturer chassis (Original CRG Share), specially developed to refine the guidance of 17 mm rockets (currents on the chassis of the categories Mini, minimal, cadet, mini 60).
The great particularity of this version lies in its internal architecture to double bearing. Unlike standard hubs that only use one bearing at each end, this model integrates two juxtaposed bearings on each side. This technique makes it possible to double the contact surface on the rocket, offering a Distribution of colossal loads and increased rigidity of the front train. By limiting the flexion of the rocket axis during large supports or passages on the vibrators, this hub guarantees a perfect and constant geometry of your front tires.
