Magnetic bobbins are compatible with SpinOlution wheels that have magnetic flyers.

SpinPerfect SPINOLUTION Bobbins are compatible with SpinOlution spinning wheels. Please check your flyer rod size if you are ordering the 8 oz, 16 oz, or 32 oz SPINPERFECT bobbins to make sure you order the correct diameter (1/4” or 3/8” diameter flyer rod). The 1/4” diameter flyer rod is about as thick as a #2 pencil. The 3/8” diameter flyer rod is much bigger than a pencil. All 4 oz and 12 oz bobbins are 1/4”.
