Meet the Power Torque System, this time, the axle is in a single piece firmly fixed to the right pedal crank of the crankset. The perfect coupling between central pin and pedal crank is ensured thanks to the particular geometry of the two components.
This solution also makes it possible to eliminate the potential play between the different materials.
To make the bottom bracket more efficient, Campagnolo also worked on the inner part. Thanks to an elaborate sequence of thickness's, it was possible to obtain an incredibly light axle while offering an absolute response in terms of rigidity.
Following a series of studies conducted by the Campy Tech Lab engineers, material was removed in the zones that could be lightened but at the same time the points of maximum stress were strengthened. Only in this way was it possible to achieve such a high technical value.
A careful working out of the dimensions made it possible to maintain the lateral measurements already defined with the "elder brother" Ultra Torque, thus guaranteeing the maximum freedom of movement and reducing the possibility of contact with shoes.
The Campagnolo engineers concentrated on ensuring that installation and servicing would be extremely simple. The most complicated work has been done, so now it's up to you to carry out four simple steps to fit the Power Torque System crankset quickly and with no potential for error.
The right-hand bearing is already locked in the axle in correspondence with the crankset; the other is pre-inserted in the left-hand cup. No special tool is required, and the new crankset is ready to propel you over endless miles.
That's right, because another one of the objectives of the Power Torque System project was prolonged operating resistance. The lab tests were very exacting in this regard. Now it's your turn.
Bicycle bottom brackets connect the cranks to the bike and allow the crank arms to rotate. There are various sizes of bottom bracket shell on the market, so compatibility needs to be checked. The three most common frame bottom bracket shell widths are 68mm (English threaded road and mtb), 70mm (Italian threaded road) and 73mm (British threaded mtb). There are also many axle shapes and styles, from JIS or ISO square tapers through to the round splined axles such as ISIS or Octalink and then there is the new external cup systems which have the axle built into the crank arms. Some frames are now using the new BB30 system which uses bearings pushed directly into the frame and removes the needs for cups to be threaded into the frame.
Besides distinguishing themselves for their unparalleled quality and performance, Campagnolo products have also become the benchmark of design. This is testified by the prestigious Compasso d'Oro award granted by the Associazione Design Italiano in recognition of the Veloce groupset, Ergopower integrated controls and Shamal high-profile wheels. Campagnolo is not only involved in the cycling world, but dedicates itself to all sports in general. In fact, it was named by the Wall Street Journal as one of the most prominent sports brands in the world. A reputation earned not only as a result of the countless successes achieved in racing competitions, but also by virtue of the attention given to quality and to service that sets this company apart from all others.
