Sized for a single chainring - perfect for the vast majority of track/single-speed cranks.
Serrated rear nut bites into the back of your crank arm so you don't have to deal with that spinny nonsense or ruin your mom's fancy butter knives trying to hold the back in place.
⚠️ These do not work on Sram Omniums, so don't even try.
