Description of Stan's NoTubes Baron CB7 27.5 Inch MTB Carbon Rim - 32 Holes

Super strong carbon trail rim that brings out the most in your high-volume tires.

The Stan's NoTubes 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 higher level of tubeless performance to wider carbon rims.

By combining a strong and light asymmetric rim design with Stan’s patented Bead Socket Tubeless technology, the developers have created the first wide carbon rim able to live up to the high standards Stan's has 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, the engineers of Stan's have developed a special version of the patented Bead Socket Technology specifically made for asymmetric rims.


Bead Socket Technology

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 most important piece to the bicycle-terrain interaction is the contact patch between the tire and terrain, so tire profile and tire pressure play huge roles in bicycle performance and overall handling. But many rims just don't work well with the tires the most riders are using. Rims that are too narrow fail to offer sufficient sidewall support and protection to your tires and create a less stable shape. The result is less control in the corners, less traction on climbs, and more rolling resistance. Rims that are too wide also distort the tire profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tire's volume. Stan's WideRight rim widths are designed to strike the perfect balance between tire volume and sidewall function.
