Bicycle Crankset Technology: Campagnolo Builds Bicycle Parts With a Difference!
Article by Luc Lacasse
Hellmuth Hirth, the young son of a German engineer, was in his early twenties when he came up with the concept of what we today refer to as the hirth coupling. This was in the early 1900′s when the maiden automotive and aeronautical industries were looking for innovative ways to joint two ends of a shaft. Today, Campagnolo is using this old technology in their newest lineup of bicycle cranksets. Seems rather humerous.
The Hirth coupling looks like a set of teeth milled on the butt end of each half of a shaft. The two ends mesh together in a self centering and self aligning locking joint. The amazing engineering of the Hirth coupling is that it offers such a high strength connection on such relatively small diameter shafts. Over the last 90 years, it has been used for reversing gears in marine engines and cooling water pumps in almost every sector including nuclear, rail, power and automotive.
Thus it is not really surprising that Campagnolo was interested in using such a proven piece of technology in their newest crankset designs.
Advantages of Using the Hirth Coupling in the Campagnolo Crankset Design:
This technology allows the axle of the new Campagnolo Crankset to be spliced in the middle of the bottom bracket shell and then the crank arms can be fused to each half axle. With a one piece half axle plus crank arm, pinch bolts to hold the crank arm in place are unnecessary. This saves a lot of weight making the ultra-torque the lightest crank in the cycling industry.
There is no need for external flanges or bushings at the joint, thus less rotational mass and greater pedal efficiency.
External bearings can now be mounted on the half spindles leaving the entire circumference of the bottom bracket shell available for a larger hollow spindle. This larger size adds rigidity to the design.
This old proven technology has allowed Campagnolo to make a major leap in crankset innovation. Further information on Campagnolo components and their innovations is discussed at myWheelsAndMore.com. including the use of sophisticated carbon fiber forming capabilities and ceramic bearing in their newest lineup of Campagnolo’s bicycle parts.
