Slot.it GI28-BZ Corona inline 28 denti Bronzo ProAxle system

ProAxle axles are tempered, rectified steel and give you the precision needed by all the ProAxle crowns and wheels. The bronze (not brass!) bushings, tailored on the ProAxle standard 3/32″ (2.38mm) axle, get rid of the sloppiness found in most off the shelf kits. The M2 set hexagonal screws keep wheels and crowns fastened on the axles, using the Allen wrench.
