The Baron CB7 is a light and strong carbon trail rim with a 35mm inner width that offers added support for wider tires, and an asymmetric design that creates a stronger overall wheel. Stan’s partnered with the carbon experts at Ibis to develop the Baron CB7 and bring a new level of tubeless performance to wider carbon rims.

It took our engineers a great deal of thought and testing to create the Baron CB7. Wide carbon rims are everywhere these days, but the truth is that most of them have real problems. Many are difficult to work with when it comes to mounting, inflating, and removing tubeless tires and don’t offer as reliable an airtight seal under impacts and hard cornering. It’s also tough to find a wide carbon rim that’s durable and light without being overly harsh. Wider, stiff rims also put more stress on spokes and hubs, leading to more frequent repairs. 

Together with the carbon experts at Ibis, our engineers developed the Baron CB7 rim to solve every one of these problems. By combining a strong and light asymmetric rim design with Stan’s patented Bead Socket Tubeless technology, we created the first wide carbon rim able to live up to the high standards we set for tubeless performance.

The Baron CB7 uses an asymmetric design with offset spoke hole drilling to improve the bracing angle of the spokes and create a more stable, wider base that offers more support for the rim. When it comes to making a strong wheel, it’s tough to beat an asymmetric design, and Ibis has been using them for years, but until now, asymmetric designs offered relatively poor tubeless performance due to an imbalance caused by the two differently shaped sides of the rim. To solve this problem, our engineers developed a version of our patented Bead Socket Technology specifically made for asymmetric rims.

With five patents and counting, Bead Socket Technology tubeless rims make it easier to install, inflate, and remove tires. BST also offers the most dependable airtight seal in all conditions.  Stan’s trademark low sidewalls are another aspect of BST the not only improves tubeless performance, but provides increased strength while saving rotational weight for faster acceleration.

The asymmetric design of the Baron CB7 also incorporates Stan’s radial impact absorbing carbon technology, RiACT. Low sidewalls and careful attention to shape and lay-up let RiACT carbon rims deflect radially to absorb impacts and vibrations, making them more durable, more comfortable and faster rolling, while still maintaining excellent lateral stiffness.

The strong low sidewalls and asymmetric shape of the Baron CB7 lets us build it to be light but extremely strong. Register your wheels with us and your Baron CB7 wheelset is backed up by our 7-year warranty and lifetime crash replacement offer. 

The Baron CB7 combines a lightweight and strong asymmetric design with the world’s best tubeless system. With the combined experience of Stan’s and Ibis, the Baron CB7 is wide carbon done right.
