Stan's Baron CB7 | M-pulse Hubs

The Baron CB7 wheelset uses an asymmetric carbon rim with a 35mm internal width built to provide added stability and control with today’s wider tires and more capable trail bikes. Extremely light and strong, the Baron CB7 relies on our BST-Asymmetric rim design to allow for more balanced spoke tension with no compromise in ease of tubeless setup and reliable airtight seal, even under the most aggressive cornering.

The low sidewalls, carbon lay-up, and overall shape of the Baron CB7 also incorporates RiACT, Stan’s radial impact absorbing carbon technology. While still offering excellent lateral stiffness, Stan’s RiACT carbon rims deflect radially to absorb impacts and vibrations, making them more durable, more comfortable and faster rolling. The RiACT rim shape, combined with the added bracing angle of asymmetrical drilling, allows the Baron CB7 rim to maintain excellent lateral stiffness and strength.

Baron CB7 wheelsets roll on M-pulse hubs that feature extremely quick 1.66° engagement and the light action and more positive lock of magnetic pawls. Unlike traditional pawl springs that are at their weakest when fully engaged and add friction and resistance when not engaged, the magnetic pawls of M-pulse hubs are at their strongest point when engaged, while offering much less drag when not engaged. M-pulse hubs also feature preload adjustment, because a tuned hub offers less drag and bearing wear than hubs that aren't adjustable. Designed and manufactured in Bend, Oregon by Project321, M-pulse freehubs are available for Shimano Micro Spline and HG as well as SRAM XDR cassettes, and are offered in all common axle sizes.
