Madd K-2 high speed titanium sealed bearings are a tough, durable bearings that will are built for extreme use.
A note about Bearings:
The difference between K1, K2, and K3 numbers, is to do with the ABEC measurement. So the higher the number e.g. 1, 2, or 3, the faster the bearing will spin. We would normally recommend K2 and above for our scooters. They are all the same size in terms of the bearing, so are able to be used in any of our scooter range.
