The 688 bearing adapter is made of aluminum.

The bearing adapter fits over your 688 mini bearings so they can be used in a 608 wheel hub. You need 1 adapter per bearing.

There are two advantages to using mini bearings.

  1. You create a much lighter setup as a 608 bearing weighs 12 grams compared to a mini bearing at 4 grams and an adapter at 1 gram
  2. Mini bearings spool up faster than regular 608 bearings

 You need 16 adapters for a set of 8 wheels
