Tekno RC bearing sleeve set
Tekno RC have introduced a bearing sleeve set for 8x14x4mm ball races. These bearing sleeves will save 1.3g of rotating mass per bearing meaning outfitted on all three differentials on a typical 1/8th vehicle, they are saving 7.8g of precious weight. The bearing sleeves are compatible anywhere an 8x16x5mm bearing is used, however, Tekno mostly recommend them for differentials. The set included six bearing sleeves and it is available now.
