My sister got it and gave me a brief description over the phone. She's not into bikes so I couldn't get a ton of info (you mean this hangy thingy in back? - when asking about RD) but it has Shimano 600 RD and FD. I'm pretty surprised because I thought Nishiki was pretty loyal to Suntour. Crank says Custom. That's about all I know now. I won't get to see it in person for over a week!! Suspense!
