The Road War — Shimano
The Road War -- Shimano vs. Campagnolo Campagnolo is known worldwide by metallurgic enginneers as a company that has developed some procceses that nowadays are used by many high precision mechanical devices manufacturers. And the Record is a summary of the most advaced ones. Campagnolo uses both cold and heat forging techniques depending on which piece. Sometimes, using the extremely high forces that cold forging procceses need result in microfissures, only viewable by very powerful microscopes, depending on which alloy is used, so sometimes is better to use a less plastic alloy and forge it at a higher temperature, submiting later the piece to a heat treatment proccess that avoid inner stresses that could appear.
