First of all a little warning: if you choose these bearings, then you will need probably bearing adapters
Why do mini 688 bearings
exist while all wheels are suited for standard 608 bearings? Simple: because they are smaller they weigh a lot less.
One Wicked Jesa Swiss Mini 688 bearing
only weighs 3.6 g, while a normal 608 bearing weighs at least 10 g and a lot of 608 bearings weigh 20 g and more.
Bearings are the heaviest parts of inline skates and you need 16 of them for a pair. That counts.
Because the bearings are superlight, they accelerate faster too.
These Wicked Jesa Swiss Mini 688 bearings
are the benchmark of performance bearings around the world. Fast and long lasting.
