Review on Universal Extenders Aluminum Adapter Motorcycle by Mufti Capers

Typical Chinese product designed and manufactured: imitate a respected brand (Ariete) and mass produce it at a lower cost. This is a decent "90 degree" valve stem if you need a quick and inexpensive one. The problem is in the rubber O-ring. It's too thick at the base of the stem and doesn't allow the stem to go deep enough into the rim/wheel. Therefore, the threaded portion of the shank that protrudes into the rim on which the nut rests during installation is insufficient to hold it securely. All I could do was install one valve stem and strip the threads on the other.
