Capricorn have introduced their new Brain Stuff brand, dedicated to quality materials, technical solutions and R&D. Their first product is this tire additive applicator which helps apply the additive to the tires. An electric motor runs at a constant speed rotating the tires placed on the first axis and contact the other two tires which will run in the opposite direction. An adjustment on the two cams allow you to set the pressure between the tires and choose the type of additive penetration. Works with 1/8th and 1/10th tires.
