Gears are often shifted under heavy load, creating enormous strain on the chain. The new X9e and X10e chain models for 9- and 10-speed derailleurs were developed exactly for this kind of heavy-duty use. Specially designed inner and outer plates, together with particularly strong pins, provide high tensile strength. The X-Bridge technology guarantees optimal performance, even when shifting under load, while preventing the enormous forces from being transmitted to the pin collar.
Statement by the Jury
The ECO chains are characterised by high-quality construction for demanding cycling, combining stability with quick and clean gear shifting.
