Ninja Minimizer Adaptors (608 to 688)
Carbon Fiber Adaptors
The mini-Miser is a revolutionary new ultralight bearing upgrade system. It takes the place of a standard 608 bearing in all industry standard skate wheels. Consisting of the incredibly light, yet strong, high performance 688 Mini-Miser spacers.
The system can be easily transferred from one set of wheels to another and once the upgrade sleeves and spacers are installed. And then only the bearings need to be occasionally replaced as with conventional 608s.
The 688 mini inline bearing adapter is made of Carbon Fiber. The bearing adapter fits over your 688 mini bearings so they can be used in a 608 wheel hub. You will need 1 adapter per bearing.
There are two advantages to using mini bearings.
First 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
Second Mini bearings spool up faster than regular 608 bearings
