In early 1900, the link Hirth Hirth joint venture or born out of DIY Hellmuth Hirth, the young son of a German engineer. It was with the development of new and emerging technologies for the aerospace industry first fascinated. Hellmuth Hirth coupling developed as a common high-strength block is used primarily for two sides of a steel shaft of the gasoline.

Looks like a series of white teeth in the profile cut end of each half. A meshtogether in a self-centering and self-adjust the cover common. Technology wonderful Hirth coupling is that it has a high-power supply on a relatively small diameter trees. Since then it has been used to reverse in marine applications and pumps for cooling water in almost all sectors, including railways automotive, and nuclear.

So it is not surprising that Campagnolo was interested in their most recent projects cranks for the use of technology such evidence. Ithas a long history of resistance testing and reliability in the most extreme environments, from navy nuclear power.

Benefits of using Hirth Coup in Campagnolo crank design:

The axis of the new Campagnolo crank may be in the middle of the range will be flat out

No need for external flanges, connectors, so less rotating mass, improved efficiency of the pedal and smooth ride.

Bearings can be mounted on trees outside half, leavingentire circumference of the bottom bracket shell is available to a large vacuum chuck. Higher the spindle train more rigid.

Campagnolo crank arms, each axle half should be merged, so there are no bolts necessary to handle links. This reduces the weight of making the ultra torque cranks of the lightest in the industry.

The last advantage of using a Hirth joint in the Ultra-torque Campagnolo cranks that can market themselves as the easiestcrank installed in the field. With traditional tools, bowls can be entered, followed by the drive shafts and a bolt 10 millimeters to keep everything in place.

Although this particular component Campagnolo tech took the border to offer motorcycle enthusiasts something to talk about.
