Stan’s NoTubes introduces new carbon rims and wheelsets

Stan’s NoTubes has introduced the new Flow CB7 and Baron CB7 carbon rims and wheelsets, featuring a new asymmetric version of Stan’s patented Bead Socket Technology (BST) tubeless rim design developed in partnership with Ibis Cycles.

“Asymmetric rims with offset drilling allow for more balanced spoke tension and a stronger overall wheel, but until now, no asymmetric rim has been able to match the lightweight, easy tubeless tyre installation and inflation and reliable airtight seal of a genuine Stan’s BST tubeless rim,” said a statement.

“The new Flow CB7 and Baron CB7 combine the benefits of an asymmetric rim with the low weight, reliability and ride quality that have made Stan’s the leader is tubeless rim design.”

Flow CB7
The Flow CB7 is a lightweight carbon trail rim featuring a new asymmetric version of Stan’s proven Bead Socket Technology rim shape. The new carbon Flow CB7 relies on an added lay-up process to increase strength while keeping weight to 420g for the 27.5in rim and 455g for the 29in model. The 29mm inner width of the Flow CB7 is optimised for 2.35in to 2.6in tyres.

Like all Stan’s carbon rims, the shape and layup of the Flow CB7 are rooted in radial impact-absorbing carbon technology (RiACT), engineered to absorb vibrations, resist pinch flats and withstand impacts while maintaining lateral stiffness for improved control. The new asymmetric shape’s offset drilling improves spoke bracing angle, further increasing the Flow CB7’s lateral stiffness and overall strength.

Baron CB7
The Baron CB7 incorporates the same new asymmetric Bead Socket Technology as the Flow CB7 for added strength and lower weight, but its 35mm internal width makes it an “ideal choice for even wider tyres”. Despite being 6mm wider than the Flow CB7, the new Baron CB7 shares the same low weight (420g for the 27.5in model and 455g for the 29in model). Unlike the Flow CB7, which is optimised for tyres as narrow as 2.35in, the increased air volume of 2.5in and similar larger tyres offer more protection for the rim, allowing the weight of the Baron CB7 to be kept as low as possible.

The Baron CB7’s rim also incorporates Stan’s RiACT technology to absorb impacts and vibrations for improved durability, speed and control. The 41mm external width of the Baron CB7s takes full advantage of the offset spoke drilling of Stan’s asymmetric Bead Socket Technology, allowing the spokes to approach the rim at an angle that gives better support for the wider rim.

Wheelsets
The wheels are built in Stan’s New York headquarters with replacement parts available directly from notubes.com and many local dealers. The Flow CB7 and Baron CB7 wheels include Stan’s newest Neo hub with Durasync 6-pawl freehub for quick 10-degree engagement and triple freehub bearings that better distribute axle load.

Neo hubs shells are 100% CNC-machined for precision and roll on low-friction centerless ground axles for long life and reliable performance. Combined with mechanically locking Secure Lock nipples, Sapim spokes allow for a light but strong wheel. Like all Stan’s wheels, the Flow CB7 and Baron CB7 rely on conventional J-bend spokes. The wheelsets are available in both 27.5in and 29in sizes to fit every common axle style and weigh 1,674g and 1,761g, respectively.

Flow and Baron CB7 wheels will be available with custom decal colour options and multiple build configurations as a part of Stan’s Custom Wheel Builder at notubes.com/custom-wheelset.

Warranty and availability
Stan’s NoTubes has announced a new seven-year warranty and lifetime crash replacement on all carbon rims registered by the original owner. This new extended seven-year warranty applies to all Stan’s carbon rims, including new rims as well as those previously registered. Owners who register their carbon rims are also eligible for Stan’s lifetime no-fault crash replacement offer.

Baron CB7 rims and wheelsets are available now. Flow CB7 rims and wheelsets will be available in November.
