How do I lube (or maintain) a Schlumpf Crankset?
• Lubrication is always done by removing the slot screw on the right side or one of the hex screws (mountain-drive with steel spider). • The Speed-Drive has two disks behind each other, where lubrication has to go through to reach the gear room. Turn the cranks until you see another hole underneath the first one. • A detailed manual can be downloaded from our Help Guides > Owners Manual Resource Archive.
