A tough, responsive carbon rim built for modern gravel riding. Circos balances low weight with the durability you need for long mixed‑terrain days, loaded bikepacking, and the unpredictable surfaces that define real‑world gravel. Lace it to your favorite hubs, pair it with Teravail tires, tape, and valves, and you get a clean, dependable tubeless system with a dialed ride feel.
What Makes It Different
Circos is designed around the wide‑tire, high‑volume reality of today’s gravel bikes. The hookless profile and reinforced construction handle washboard, chunky connectors, and fast descents without flinching. The rim shape supports stable cornering, predictable compliance, and confident handling when the terrain gets loose or rough.
Bakersfield Notes
From the hardpack out toward the riverbed to the sandy stretches on the way to the foothills, Circos hits the sweet spot: stiff enough to stay precise, forgiving enough for long days, and strong enough for the surprise hits that come with local gravel.
