ENJOY THE PERFORMANCE

LA555

More aerodynamics, more integration. You are battling with the wind with every turn of your pedals. A battle you will no longer have to fight, so you can start enjoying yourself. Only cyclists know that feeling of performance, power and efficiency that we achieve when body and machine are working at 100%. The addiction to speed. More info

AERO FEELINGS

The sensations we pursue with the new RS1 are speed, performance, and ergonomics.
In our development process for competition frames, aerodynamics is a fundamental pillar. Years have been dedicated to thorough studies, prototype creation, and simulations to ensure maximum performance and ergonomics designed for long distances.

KAMM TAIL SHAPES

The Kamm Tail shapes in the tube sections make the RS1 a 100% aerodynamically efficient bike.
The aerodynamic design ensures that air flows without generating pressure zones that could affect our speed or the effectiveness of the watts applied. In other words, we have optimized every effort to ensure exceptional performance with every pedal stroke.

PERFORMANCE CARBON LAYUP

BH's technique for frame construction—Hollow Core Internal Molding—involves internal hollowing and high pressure to achieve the highest levels of compact material, eliminate inconsistent pressures, and prevent bubbles and imperfections in the carbon.
Additionally, we use Performance Carbon Layup, which maximizes the bike's lightness-to-stiffness ratio.

STIFFNESS AND REACTIVITY

In the RS1, we have expanded the bottom bracket shell to 86 mm to maximize stiffness. We have optimized the frame tubes to maintain maximum rigidity with minimum thickness.
The RS1's shorter chainstays are a key element for its agility and responsiveness.
This unique combination of agility, responsiveness, and aerodynamic efficiency makes the RS1 an outstanding choice for cyclists seeking optimal performance on any terrain.

NO VISIBLE CABLES

The frame is clean with all the cabling 100% internal through the ACR system.

HIDDEN QUICK LEVERS

In line with integration, the RS1 features hidden quick-release levers, allowing for tool-free wheel removal while maintaining a clean aesthetic and improved aerodynamics.

ESSENTIAL COMFORT

The RS1 adopts a specific geometry to make its ride comfortable for most cyclists. The front end is higher thanks to a taller head tube, allowing for a comfortable position while maintaining a racing aesthetic.
The rear end balances agility, quick reactions, and descending security. This makes the BH RS1 a bike that combines high performance and comfort, ideal for long days in the saddle, gran fondos, and intense weekend rides.
