All ENVE Wheels must use approved spoke nipples manufactured by Sapim and/or Alpina. These spoke nipples are designed to work in conjunction with our patented molded spoke nipple seat. 

You can find those spoke nipples on our website here: https://www.enve.com/product/spoke-nipple/

• Use of any other spoke nipple or washers may potentially cause damage to the rim and void the warranty. Spoke prep is not required.
