RR90 _ Innovation and building technique.
Radial brake master cylinder RR90

From a single top quality aluminum block, we have created this innovative radial brake master cylinder.
A brake master cylinder that provides increased performance but maintains all the standard functions.


  • Built-in oil tank
  • Ergonomic and adjustable lever
  • Inner bushing in bronal which ensures no oscillations on the lever
  • The brake light switch is incorporated.


The anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish.
Our black anodized products are well-known for their black maintenance during the years (they don't become grey or violet).
Our secret is an indelible black pigment we use in this treatment that maintain the colour also at high temperatures.
The same for all other colours.

This option finish comes after the anodizing process.
The all black piece is CNC machined and the raw aluminum gets up to the surface to create a design and a movement on the piece.

We are the Artisans of Exclusivity.
