The groupset arrived today, as expected no additional fees to pay so 392€ is the final price. There is in fact no region lock or anything like that so pairing the groupset to the phone was no issue. Installation was pretty straightforward. The only negative are the rubber hoods that are hard to pull making it a little difficult to reach the clamp screw. The brake hoses were pre filled and i took care to not spill any oil when installing. This way i managed to not have to bleed them myself. They brake perfectly just like that. For the shifting i just did the initial setup and some b-screw adjustments and it shifts really well. Haven’t even looked into fine tuning the single gears as it just works. I will probably have a look at it to make it 100% perfect but it doesn’t seem to be necessary right now. I did a first ride and yeah - it just works. There‘s really not much more to say. I expected a really tricky and annoying setup but nope.
For those also having the magene pes p505 here‘s an interesting information: the charger of the derailleur and the charger of the magene seem to be the same interface. I haven’t compared them directly and didn’t try it out but they look very similar. Would be pretty convenient if you are travelling for example and have to carry only one cable.
