I just took a look at the Vilano website. I'll guarantee they do not sell any bikes with sew-ups. That's not their market. Your bike has clinchers. Make sure you get a tube with the correct valve stem, I bet your bike has Presta valve stems. That you can tell from the outside, just by looking, without having to take anything apart. This is the most common valve stem for anything above a hardware store quality bike. Cars, motorcycles, and really low end bikes run Schrader valve stems.
