I just recently bought a bike from someone who purchased it in Japan. But I don't know what it is and can't seem to figure it out. It is a road bike with "Re: turn off" stickers all over it. There is also a "chaos" sticker on it. Near the crankshaft there is another sticker, "alumi 7005 return off". Another saying "rd-700". It has a Shimano 7sis rear derailer. The serial number is JH00606969292. If anyone can help me I would greatly appreciate it.
