Deore rear derailleur RD-M592 by Shimano - with a flat profile

The Shimano Deore RD-M592 is a 9-speed rear derailleur with Shadow profile. This means it is designed so flat that the risk of snagging is reduced to a minimum, especially as the single preload prevents it from hitting the chainstay. The rear derailleur also impresses with its crisp shifting thanks to a stronger return spring.

Shadow RD
Shadow rear derailleurs from Shimano have a very flat profile, allowing for a more aggressive riding style by minimising the risk of getting stuck on obstacles. In addition, the single preload ensures that the rear derailleur does not hit the chain stay even on very uneven ground. All of this contributes to a quiet, clean-operating gearshift.

Using it for 10 years and still works perfectly! Originally used mostly on roads and just sometimes in forests but nowadays I fully use it in forests. Up and down, up and down with harder usage than before.

Shifting was always precise and fast without any problems.

Really loved it.

В эксплуатации 2 года в режиме ежедневного транспорта в любую погоду и для долгих поездок. Установил и настроил без проблем, переключения быстрые, точные. Вся остальная навеска также Deore. Но всё же не хватает плавности и тишины вращения роликов. Надёжности хватает, не вышел из строя при попадании ветки.
