Wheelsmith Spoke Prep Single 15ml Jar
Ask any wheel builder and they'll tell you Wheelsmith Spoke Prep is the secret ingredient to building a solid and reliable set of wheels. Spoke Prep's Teflon-infused secret formula acts as both a lubricant and a thread locker.
If you are going to be building wheels you will need this to keep spokes from chronically loosening. 1 "tub" should be more than enough for most people. If you really need to you can use little colored start stickers to distinguish between right and left side spokes when assembling.
