Answer Question
Crank Brothers recommends high quality marine grease when servicing pedals on the spindle body. The Igus bearings are self-lubricating and do not require any grease. Crank Brothers specifically recommends Sta-Lube SL3121 Marine Boat Trailer and 4 x 4 Wheel Bearing Grease - 14 wt. oz. in this video (Crankbrothers Pedal Refresh Kit Installation Tutorial). Park Tools recommends their own HPG-1 Park Tool High Performance Grease as seen in this video (How to Rebuild Crank Brothers Pedals)
