BH Bikes SL1 4.5 - Carbon Roadbike - 2026 - light grey / white / lime

Performance, lightness, and comfort with every mile.

The new BH Bikes SL1 combines lightness, efficiency, and comfort. Designed for those seeking long-distance rides without sacrificing the agility and racing DNA of the BH road bike family. The SL1 frame uses Toray T400 carbon and HCIM technology ( (Hollow Core Internal Molding)), which is reserved exclusively for BH ’s high-end road bike frame. This technology optimizes wall thickness in critical areas, eliminates bubbles and imperfections, and ensures maximum material compaction. The result: a lightweight, stable, and high-performance frame.

The full-carbon fork was developed to improve aerodynamics and vibration damping. The fork offers more clearance between the tires and the fork, optimizing airflow. It is compatible with tires up to 32 mm, and even 35 mm on some models, to meet today’s demands for comfort and performance. The compact rear triangle design improves responsiveness and power transfer.

The bottom bracket with the BB386EVO system increases the diameter of the lower diagonal tubes to up to 80 mm, reduces wall thickness, and increases torsional and rear triangle stiffness.
