These pulleys will just not stop spinning! Don't take our word for it, just listen to our friend and badass racer Allison Linnell, doing a full spindown on video right here.

The name of these pulleys came from the fact that Instagram videos were limited to 15 seconds. There is no way to show how well they spin in 15 seconds. Since then Instagram has lifted the long video ban and Kogel is looking to rename this amazing product. Send us your suggestions!
