The PBR rowel is the most commonly used rowel in the bull riding industry today.
This is a "Self Locking" rowel.
Bull riding rowels are like guitar strings. The more you use them eventually you will need to replace them. Depending on how many bulls you get on in a year you should always change out rowels every 6 months to a year.
