This is an SD2.0 integrated upper deck. I bought it new a while ago, but ended up changing the specifications and no longer need it, as I didn't use it much. Made by Warabiyama Carbon. This integrates the split front and rear upper decks of the SD2.0! This product is for SD2.0, but it can also be mounted on the main chassis of the YD-2 series and RD1.0 with the RD2.0 mission case and SD2.0 aluminum mission case, expanding the selection of rear-end items! t: 2.0mm (±0.1) Twilled weave, matte
