HeyYou Posted February 24, 2014 Posted February 24, 2014 Who was the lucky Sod that got the Bianchi, Deltas and the other goodies? Come on, own up!
Cippo Posted February 24, 2014 Author Posted February 24, 2014 Who was the lucky Sod that got the Bianchi, Deltas and the other goodies? Come on, own up! Eish, I offered to help him with the Deltas. I would love a pair to call ' my precious'. Someone in Jhb probably got the treasure.
Cippo Posted February 25, 2014 Author Posted February 25, 2014 A little EPS history.The first version of the project dates back to 1992 and develops from a partnership with the illustrious Professor Magnifico, who is none other than the teacher of Mr. Faggin, engineer, father of the MicroChip. ERGOPOWER: with a switch on lever 2 to go up on the sprockets, whereas a button inside the grip allows you to go down. FRONT DERAILLEUR: driven by an electric motor with the application of 2 contact limit switches. The derailleur goes from the first to the second chainring by moving from one limit switch to the other. REAR DERAILLEUR: with an electric motor positioned in the parallelogram. The system uses a mechanical cable that operates a linear optical led encoder located under the shell that is mechanically operated by a cable extending from the rear derailleur. This solution allows the resetting to zero process to be completed as with the mechanical drivetrains. ELECTRONICS: located in the encoder. It is an electronic digital component that reads the position, the speed and the direction of a part in motion and translates this data into a binary code in output. The system does no more than receive input, translate it and control the movement of the rear derailleur. BATTERY: The power supply is provided by normal AA Ni-Ch batteries, in the place of the water bottle cage. Difficulties encountered:- infiltration of water inside the electronic "brain“, caused largely by its position under the shell.- the led optical encoder is not very exact and generates problems with the alignment of the rear derailleur.
Cippo Posted February 25, 2014 Author Posted February 25, 2014 Starting with release 1, the engineers in the Campagnolo research and development department began to work on a number of technical solutions that brought us to the second release in 1994.FEATURESERGOPOWER: envisions the use of only keys: 1 key on lever 2 to move up and 2 separate keys to move down, that can be used alternately, and positioned in such a way that they can be reached in all riding positions. FRONT DERAILLEUR: controlled by a specific gear motor equipped with an optical led encoder built into the derailleur itself. This is done with the aim of making shifting faster and more precise, and allows the movement and position of the drop out to be controlled and monitored. REAR DERAILLEUR: re-considered, eliminating the mechanical cable that initially indicates the position to the encoder by including a new and more sophisticated type of optical led ENCODER inside of it. BATTERY and the ELECTRONICS: positioned inside the seat tube. A first, semi-handcrafted version is also developed, with a digital display. YEAR19948 SPEEDStarting with release 1, the engineers in the Campagnolo research and development department began to work on a number of technical solutions that brought us to the second release in 1994.Difficulties encountered:The choice of positioning battery and electronics in that very spot is innovative for its time, but requires particularly long electric connections that lead to a loss of power and do not allow the operations of the derailleur to be carried out.
Cippo Posted February 25, 2014 Author Posted February 25, 2014 1997 was the year that marks the transition between the traditional mechanical drivetrain from 8 to 9 speedsFEATURESERGOPOWER: does not undergo variations with respect to the previous version. REAR DERAILLEUR: designed to work with 9-speed sprockets, with more limited tolerances and a greater stroke that requires greater precision in processing and planning. To increase the shifting speed the power of the electric motor that operates the rear derailleur is increased. ENCODER: it is rotative using a friction sensor to increase the shifting precision even when subjected to the stresses and vibrations generated by the asphalt.
Cippo Posted February 25, 2014 Author Posted February 25, 2014 2000 was the year the 10 speed Campagnolo mechanical drivetrain comes out on the market.FEATURESERGOPOWER: the buttons are eliminated, but levers 2 and 3 are introduced to go up and down on the sprockets and to make the controls for the future electronic system match the Ergopower controls developed for the 10 speed mechanical drivetrains. FRONT DERAILLEUR: re-designed moving on from a worm screw and rack system. The initial friction, rotative type encoder becomes a magnetic one, increasing the capacity and precision of translating the impulses into digital data. REAR DERAILLEUR: rigidity and response are increased by the massive use of the carbon fibre. Even the ENCODER of the rear derailleur is replaced with a rotative magnetic one to increase its level of precision. BATTERY: removable and built onto the side of the water bottle cage. ELECTRONICS: housed inside a base that is designed expressly for this purpose. The brain of the system communicates with the new cycle-computer that integrates the entire diagnostics system and creates an interface between the system and the cyclist.
Cippo Posted February 25, 2014 Author Posted February 25, 2014 2005FEATURESFRONT DERAILLEUR, REAR DERAILLEUR, ENCODER: untouched ERGOPOWER: re-designed. Lever 2, dedicated to the up shift of chainrings and sprockets, stays the same, while lever 3 is replaced by a button that controls the down shift. BATTERY: designed expressly for the electronic unit with a transition to polyamine Lithium-based technology that is long-lasting and provides improved performance. It is re-positioned at the feet of the water bottle cage using a different coupling/uncoupling system and new types of connectors. ELECTRONICS: re-positioned at the base of the water bottle cage with an advanced system of wireless communication that is developed between the components with the aim of eliminating the presence of cables on the bike. Difficulties encountered: Infiltration of water.
Cippo Posted February 25, 2014 Author Posted February 25, 2014 An industrial pre-serial of the latest version of the Campagnolo electronic drivetrain branded as “Campy Tech Lab” is used during the 2011 competitive season by the Pinarello Movistar team, winning two titles at the Giro d’Italia, 1 at the Tour de France and 1 at the Vuelta di Spagna. November 7, 2011 – the era of the EPS Electronic Power Shift begins.
