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.
I've been using the same little vat of this goo for a few wheelbuilds now. Great product and much better than using standard anti-sieze. Remember, no gluing spokes! Without proper lube, spokes will not tighten appropriately and the wheel will suck forever.
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.
