Review: Yayı kolaylıkla değiştirdim. Herkesin merak ettiği soru olan alınan kahvede bir etkisi oldu mu sorusuna cevap veriyorum; muazzam fark var. Kahvenin tadı daha parlak ve orjinal yay ile aldığım shot daha acı çıkarken şu an sadece yay değişimi ile gerçekten daha parlak ve aciligi gitmiş kahve aldım.
Review: Great fit for Gaggia Classic Pro. Easy install too

## Features

- Replacement for the original spring in Gaggia Classic 2015EU/ 2018/2019/2020/Pro OPV to 9 bar for industry standard espresso extraction pressure
- Fortunately, it is relatively easy to replace the spring in the over pressure valve with a weaker one and thus regulate the pressure to the ideal 9 bar
- This pressure is too high when using a classic espresso portafilter basket. Professional espresso machines have a pressure of 9 bar
- We offer a self-assembly stainless spring that is compatible with all newer Gaggia Classic coffee machines (2019 models - so far)
- Package contains: x2 9Bar OPV spring
