Great test (I know it's older but hey, the thread is back man). I wonder how the o-rings react to various lubricants used and then the solvents?
What I mean is, what if the rubber reacts to the rider's lube of choice and then reacts to the cleaning agent because of the lube?
Chain lube spray
what else do ya-all use?
These were all 'virgin' o-rings.
Just thought I'd ask if anyone else had wondered?
