Phil Wood BB Cups – Swiss

Phil Wood threaded bottom bracket cups will fit onto any of Phil Wood bottom bracket cartridges produced since 1971. They are an interference fit with the bottom bracket, and will require Phil Wood bottom bracket installation tool to install. Cups will ship with a small tube of thread retaining compound (which must be used during assembly).
Cutting taps used to produce the bottom bracket thread in cups leave microscopic hairs and cracks in the thread form. Thread in PW cups is hand polish to all but eliminate galling between cups and the bottom bracket thread.
