Tribology is just a name for the study of friction. You all know i have a hard on for engineering concepts related to reducing glide friction between skis and the snow, but i also enjoy testing out new bearings and seeing how well they glide (roll) on skateboard. Probably the best bearings ive tried are flip hkd abec 5 and abec 7. Both are incredibly low friction and you glide as if you were on ice. Bones super swiss 6 are also very good but cost 5 times as much as the flip hkds and arent noticeably faster. Zealous and zealous ceramics are cool because they have an extended inner race so you dont need to use a bearing spacer between the bearings or speed rings on each side. They are very smooth but a little bit “sticky” is the best way to describe. They feel really good but dont feel as frictionless as the flip hkds or bones super swiss 6.
anyways, if i could give a single unit of advice i would say to try flip hkd abec 5 on your board. They cost 10-12 bucks and you will cream your pants so hard you will lose consciousness and go into a coma.
