Do the seals on cartridge bearings really make any difference? Metal sealed bearings seem to be a bit cheaper, are the metal seals any less effective? Is there any effect on the side-loads that the bearing can take (I realize that on a non-angular-contact bearing, the side loads it can withstand are very low, but still)?
I'm puttin together a big order of bearings for a few pairs of pedals and for my DH bike so I was just wondering....
