The M-Pulse hub combines the best materials and construction with an intelligent engagement system and is built to roll longer smoothly. At the heart of the M-Pulse hub is the magnetic locking system, based on the innovative Project321 design and manufactured in a high-precision, low-volume facility in Bend, Oregon. M-Pulse freewheel hub features six pawls equipped with neodymium magnets that engage every 1.66° with more force than traditional spring-based pawl designs and less resistance during coasting. With less friction and resistance. This compelling and durable technology is backed by Stan`s NoTubes 5 year warranty!
