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 and you need 1 adapter per wheel. There are two advantages to using mini bearings.
- 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
- Mini bearings spool up faster than regular 608 bearings
You need 1 adapter per bearing.
Sold individually (1 piece of adapter)
