Die Spedaos (vormals Sroad) funktionieren bei einigen hier sehr gut. Meine eine, die noch im Betrieb ist, ist jetzt 8000km gelaufen. Die Beschichtung ist selbstverständlich an den Kontaktstellen zur Kette nicht mehr wie neu. Aber noch geht alles gut, bin jetzt bei Kette #2 mit der Kassette. Bin gespannt ob Kette 3 dann auch noch gut geht. Ich hatte insgesamt 3 Kassetten: Die zweite ist wegen Umbau auf 12sp gerade im Lager, lief aber bestimmt auch 5000km unproblematisch bei jedem Mistwetter. Die dritte hatte ich samt Rad verkauft und keine Beschwerden mitbekommen.
