  • Hi guys,

    My shimano mx30 pedals have developed some play so I'd like to see a new set of bearings will fix them up. All the specs in online stores say they have sealed cartridge bearings however the service diagram from shimano shows them as containing regular ball bearings inside. Does anybody know what's actually inside so I can the right parts before opening them up??? Did they used to make them with ball bearings but newer ones are cartridge???
