This is the Elite SUITO-T smart trainer, a direct drive type. I purchased it used a few years ago, but I'm selling it because I no longer have the opportunity to use it. The missing items and other details are described in the 9th image. Parts F and G for thru-axle are missing, as well as part C for quick release. Part B is not the original one, but a Shimano low spacer Y4T724000 purchased separately. https://www.amazon.co.jp/dp/B00GH1YH4G You may need to purchase an additional one depending on the sprocket you use, but you can buy it on Amazon etc. Part C is not required if the rear end width is 135mm. If it's 130mm, part C (= 5mm spacer) is required. It seems you can purchase the original quick release parts from Amazon. https://www.amazon.co.jp/dp/B08N1FBY5Q It also seems you can purchase the original thru-axle parts from Amazon or online retailers in Japan. The power supply is not the original one, but it starts up. The riser is also not the original one, and it makes a noise when shaken, but it works. An 8-speed sprocket purchased separately is attached. If you have a quick-release bicycle with a 135mm rear end width and use the included sprocket, you don't need to purchase any additional parts and can use it as is.
