Atomik Carbon introduces Berd Ultimate Wheels

High-end carbon-fiber wheel manufacturer Atomik Carbon today announces its partnership with Berd Spokes to introduce its all-new Atomik Carbon Ultimate Berd Wheelsets. Atomik Carbon Ultimate gravel and mountain wheelsets are ultra-lightweight, starting at just 1,200 grams per pair. And by combining the uniquely compliant ride offered by Berd Spokes with the damp and precise characteristics of Atomik Carbon rims, the Ultimate Wheelsets offer the ultimate ride quality. Berd spokes, typically available only in white, are available on Atomik Carbon Ultimate Wheelsets in a limited edition Stealth Black. Custom colors exclusive to Atomik Carbon will also be available including red, blue, orange and olive green.

Known as “the world’s lightest spokes,” Berd patented spokes are made from ultra-high molecular weight polyethylene, or UHMWPE—the same material found in bulletproof body armor. Not only does this advanced polymer have superior damping properties to minimize impact and vibration, but it also has 12 times the strength-to-weight ratio of the steel used in traditional spokes and a superior fatigue life.


Like all Atomik Carbon wheelsets, the Ultimate Wheelsets are handbuilt. But unlike builds using traditional spokes, Berd builds are labor-intensive, with most hubs requiring a chamfering and polishing process, and three tensioning sessions, including a “rest” period of 24 hours during which the Berd’s UHMWPE material naturally relaxes by up to 50 percent before being re-tensioned. They then relax by up to 25 percent before reaching their maximum length during a third and final tensioning.

“In every test, Berd spokes had a higher breaking limit than every spoke we tested,” says Lee. “The strength to weight ratio is truly impressive.”
