These are high crush flywheels inspired by daybreak and pulsar flywheels, however they only work with stock stryfe cages (43.5 mm). I am using them in a Dart Zone Spectrum 42 mm cage, which is the cage size limit. I would highly recommend just using a 43.5 mm cage, depending on your motors (I'm running Wolverine MK-2 180 motors)
