Skip the drag, and coast with ease! Stan’s newest innovation in bicycle hubs combines top-notch materials with a smart, magnet-driven, engagement system. M-pulse hubs have been reengineered from the ground up to have you rolling smoother, longer.
A Magnetic Heart
The heart of M-pulse hubs is the magnetic-locking engagement system based on the ground-breaking Project321 design. Manufactured in a small-batch, high-precision facility in Bend, Oregon, M-pulse freehubs feature six pawls equipped with Neodymium magnets engaging every 1.66°. This design offers substantially more force than traditional spring-based pawl designs, and costs you much less drag when coasting. With decreased friction, Stan’s new M-pulse hubs spin more freely than any other hub on the market, and rolls further, faster, with less effort.
Stan’s believes an innovative design is only as good as its materials and construction. So each detail of the M-pulse hub has been engineered to remove the weaknesses in traditional pawl and ratchet-style hubs.
