Combined with launch of this F-05 Front Multi-Roller product (15808), DR-EVO Multi-Mount right back Body (15341) and DR 11mm Aluminum Passing Roller w/ incorporated Ball Bearing (15342) how many ball bearing related option elements for Dangun Racers have actually in reality in fact increased quickly. To be able to provide more ball bearing options, Tamiya now releases 2 kinds of ball bearings specifically for Dangun Racers. Each set includes 2 bearings.
