Riding the Wind. On a Swell.
Like a surfer reading the wind, breathing with the sea, and surrendering to a single wave. Reading the rhythm of the city, cutting through the wind, and drawing your own unique line.
From races to streets, for riders who care deeply about performance.
For those who aren’t satisfied with their current custom setups and are seeking the next upgrade.
BROTURES now launches a carbon rim built on pure performance meritocracy.
BROTURES SWELL CARBON RIM
Want to take your fixed-gear ride to the next level. Faster. More fluid.
The SWELL rim relivers high performance in all conditions, and was designed with reference to pro-spec rims used in modern global racing.
What stands out is its wave-shaped design, engineered for aerodynamic advantage.
That wave-like profile disperses wind pressure when exposed by crosswinds. minimizing wobble or instability — common drawbacks of carbon wheels in city riding. The result is a stable, confident ride, no matter the wind direction or weather.
Furthermore, the wave form provides an excellent stiffness balance.
Raised rim segments at each spoke hole distribute the pull forces evenly. Compared to rims of uniform height, it’s lighter and less prone to wobble.
In other words, this rim delivers exceptional performance in any condition while remaining tough and stable — a product created as “the most advanced carbon rim ever made for fixed-gear,” surpassing even the BROTURES F rim.
Rim Options
You can choose from two rim-height versions:
SWELL 4045 — a shallow rim that emphasizes weight saving. Great as a responsive wheelset for riders who navigate frequent stop-and-go traffic in the city.
SWELL 5560 — for riders seeking superior speed retention and a bold visual impression. It reduces drag during straight-line cruising and enhance sustained performance.
For meeting modern demands, it also supports tire widths from 25 c to 50 c.
If you're ready to move on from your current custom setup and pursue the latest trend with serious intent — we’re ready to take your order.
