Habe dieses Tretlager bereits einmal bestellt um das Vorgängermodell von Shimano zu ersetzen, nachdem es unerträglich knarzte und nicht mehr sauber und geschmeidig lief. Nun ersetze ich es bereits wieder nach nicht einmal 1,5 Jahren erneut. Nach nicht einmal 12 Monaten begann es bereits wieder zu knarzen und lief erneut unrund - verträgt es womöglich den Winter nicht?
