Revolutionary modular bottom bracket composed of hollow aluminum cranks, 30mm aluminum bottom bracket. and oval chainring and direct mount spider assembly.

The spider is fixed to the central axis by means of a groove that allows a total adjustment of the OCP of the Q-Rings.

As the plates and the spider are carved from an aluminum block, maximum rigidity and lightness are achieved.

Weight: 599gr

The ALDHU name comes directly from the racing legacy; is an abbreviation for Alpe d'Huez to commemorate ROTOR's first and iconic Tour de France victory with Carlos Sastre in 2008.

Revolutionary new modular technology for Rotor's lightest crankset to date: 599g.

The ALDHU technology revolves around a 30mm 7075 CNC aluminum bottom bracket. in diameter, to which the hollow 7055 CNC aluminum cranks are attached, at each end, and the spider-chainring assembly, by means of its revolutionary direct mount grooving.

The system for fixing the chainrings and spider to the bottom bracket, in addition to providing enormous rigidity, allows you to adjust the OCP (Q-Rings ovality) with great precision, thanks to its multiple grooves.

The ALDHU 3D + cranks employ an improved and lighter version of the Trinity triplicate casting, which drills three inside holes. This allows the connecting rod to support rotation and resist bending more effectively than a single-cast one.

The 100% CNC aluminum construction goes beyond simply using fashionable materials, as it remains true to its goal of delivering unrivaled performance at its weight level. In this way, it offers the rigidity of aluminum with a lower weight than most carbon cranks!

But the greatest advance in stiffness and lightness is achieved with the innovative idea of, starting from an aluminum block, CNC carving the spider and chainrings in a single piece.The icing on the cake is the direct mount system with multiple grooves for fixing. from the spider to the bottom bracket.

The end result of all this technological deployment is Rotor's lightest and stiffest bottom bracket set, without sacrificing groundbreaking aesthetics.

The ALDHU bottom bracket system is compatible, through the corresponding cups, with BB30, BB386, BB86, PRESS FIT 30, PRESS FIT 4130, PRESS FIT 4630

The connecting rods are manufactured in three different lengths: 170 / 172.5 / 175 mm.

The plates are oval 50/34 in solidarity with the spider. Consult other combinations.
