For the past 18 months or so I've been riding with MKS Lambda / also known as Rivendell Grip King platform type pedals. My primary commute bike has racked up many thousands of miles with these pedals, and it's about time to have a look at the insides to clean them up, maybe swap out the ball bearings, grease them up and adjust bearings. Only problem is the plastic cap on the outer side of the pedal axle does not look like it can be removed without destroying it or doing a lot of damage to the plastic. Many other MKS pedals have threaded metal caps over the pedal axles which can be removed and replaced for servicing. So anyone ever done some inside bearing maintenance on grip king pedals (or other pedals with a plastic semi permanent looking cap)? What's the trick for getting past the plastic cap without ruining it?? Thanks in advance.
