The pulley wheels are metal. I checked them thoroughly to see if there were any nicks that would abrade the lines. They are very smooth. The body is plastic. The wheel and the shaft are one piece that turns together - no ball bearings.

I purchased the kite on Ebay so I don't know if Best would even consider a warranty issue. I'll contact them anyway to see if they have a better replacement.

Thanks,
Jake
