The ultimate spoke thread compound is Wheelsmith Spoke Prep because it is both a lubricant and a thread lock! How can it do both? When spoke tension is low and there is risk of loosening, Wheelsmith Spoke Prep "locks" the nipple by maintaining a minimum nipple torque. When spoke tension is high Wheelsmith Spoke Prep keeps nipple torque low with Teflon lubrication. Wheelsmith also have Spoke Prep in two colors so you can prep your spokes and immediately know on which side of the wheel they will be used. Sold Individually.
