Smok TF-R1 is the single coil RBA system for the TFV4 tank. The coil is wrapped at 0.8 ohms resistance. The single coil system features two posts on either side of the head.
The assembly consists of a coil head that can be built out according to your specifications. The deck is a good size and offers enough working space for an expert builder to build with ease. Both RBA kits include a pre-built deck, as well as extra pre-wrapped coils, replacement screws and a pad of organic cotton. Imported.
