Poly-BD wheel with 3-spoke metal hub.
The 3-spoke slotted hub is the lightest aluminum hub available which is wrapped in the very best Poly-BD formula for top skaters who demand performance. The "Speed Groove" allows the urethane to react to quick moves in opposite directions.

From Radar Wheels - Metal Hubs offer the tightest tolerances and the best performance for roller skate wheels and metal bearings. You must lubricare the bearing seat inside the hib and the outside of the precision bearing with WD40 or a silicone spray before inserting the bearing. We suggest using a bearing press or inserting the bearings slowly by hand. The bearings should never be forced into the metal hubs.
