Das Lager ist sehr gut. Es ist deutlich besser abgedichtet als der Vorgänger und beide Schalen sind aus Metall.

Nach etwas mehr als 12 Monaten hat die Achse starkes Spiel. Qualität scheint bei Shimano rückgängig zu sein. Würde empfehlen ein anderes Lager zu kaufen.

Nach 2500km und 7 Monaten bereits so viel Spiel, dass das Lager ersetzt werden muss.
Das Shimano Vorgängerlager hat 46000km gehalten.

Preis/Leistung top, solide und kompatibel - gut für Trekking und City und damit für eigentlich alle alten Räder, die noch eine Vierkant-Garnitur fahren

Preis Leistung ist top, aber ich habe schon mehrere davon verschlissen, weil sie mit Regenwasser in Berührung gekommen sind. Aber da das auch die teuren nicht überleben,
ist dieses hier perfekt. Also am besten, den Regen zügig abtrocknen lassen und nachfetten.
