These flyers will fit Kromski Prelude, Interlude, and Sonata Spinning Wheels. The flyer does NOT come with a bobbin but Kromski's regular bobbins fit this flyer. The Faster Flyer extends the high end ratios of your wheel. These faster speeds, coupled with the joy of spinning on a Sonata, Prelude and Interlude, give you the feeling of a production wheel. Use the regular bobbins with the Faster Flyer. If you want additional bobbins they are also in stock and listed here:
