Radar Diamonds

Mounted on stiff aluminum hubs for maximum feedback, made of Poly-BD material.
We will warn you that these wear down fairly quickly, probably due to the narrow profile combined with the stiff metal hub, especially if you skate on a hard or concrete floor. That being said, if you are looking for a VERY slim wheel, these are among as slim as they make.
Grey = 90A
Red = 92A
Natural (White) = 94A
Green = 96A

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.

Price is for pack of 4 wheels.
