688 Mini Bearings

The Bont 688 Quad Mini roller skate bearing has an exceptionally fine polished bearing track surface and incredibly precise balls. The lightweight plastic cages allow for lower rolling resistance. The extremely strong steel helps the bearing keep its shape when under load.
Bont 688 inline skate bearings are the bearing of choice for a number of Team Bont skaters. Quite a lot of skaters want the lightest skate setup they can possibly achieve and mini bearings can save 12 grams per bearing. On a roller skate or roller derby skate, that is a saving of 88grams when you factor in the 1 gram spacer on each bearing.
