Technology

Titanium Materials

Litespeed employs 6Al-4V and 3Al-2.5V titanium alloys for its high-end bicycle frames. The 6Al-4V alloy, consisting of approximately 90% titanium, 6% aluminum, and 4% vanadium, is used in models like the Spezia for its strength. This alpha-beta alloy provides an exceptional strength-to-weight ratio, with a density of 4.43 g/cm³ compared to steel's 7.85 g/cm³, enabling lighter frames without sacrificing structural integrity. Additionally, its inherent corrosion resistance stems from a stable titanium dioxide passive layer that forms naturally, protecting the frame from environmental degradation even in harsh conditions like saltwater exposure or salted roads.^[34]^[35]^[36] The alloy's superior fatigue resistance, with an endurance limit of approximately 500 MPa, ensures long-term durability under repeated cycling stresses, far exceeding many alternatives in high-cycle fatigue scenarios. Titanium's natural vibration damping properties further enhance rider comfort by absorbing road buzz and impacts more effectively than stiffer materials, reducing fatigue on extended rides. Its biocompatibility also makes it hypoallergenic, ideal for custom fits without risk of skin reactions or allergies common with nickel-containing steels.^[37]^[38]^[39] Litespeed sources globally procured seamless titanium tubing, which is then heat-treated to achieve optimal yield strengths up to 900 MPa for 6Al-4V, allowing for precise engineering of frame performance. The lighter 3Al-2.5V alloy, with lower density and enhanced ductility, is used in ultralight models like the Coll dels Reis. Unlike carbon fiber, which can become brittle and is challenging to repair after impact damage, titanium's weldability enables straightforward repairs, extending the frame's lifespan and making it a more sustainable choice for discerning cyclists. In comparison to carbon's vulnerability to delamination, titanium maintains its properties post-repair without significant loss in strength.^[40]^[41]^[42] Across Litespeed's lineup, alloys are applied with variable wall thicknesses ranging from 0.4 to 0.9 mm, tailored to rider weight, discipline, and tube location to optimize stiffness and compliance. This customization, achieved through in-house cold-working and butting, results in frames weighing under 1 kg for premium models, such as the 948-gram (size medium) Coll Dels Reis road frame using 3Al-2.5V, balancing ultralight construction with robust performance.^[43]^[44]^[2]

AeroLogic

AeroLogic represents Litespeed's proprietary design philosophy for integrating aerodynamic optimizations into carbon fiber bicycle frame tubing and components, aimed at reducing drag while preserving lightweight and compliant characteristics. The core concept employs Kamm-tail and truncated airfoil profiles on key tubes, such as the downtube, to streamline airflow and cut turbulence compared to conventional round tubing shapes. These profiles are informed by computational fluid dynamics (CFD) analysis and wind tunnel validation, enabling targeted reductions in aerodynamic resistance without compromising structural performance.^[6]^[45] Implementation of AeroLogic focuses on variable tube geometries tailored to specific frame areas, including deeper downtubes on road models like the C1 for enhanced frontal area efficiency. Integrated cable routing runs lines through the frame to eliminate external protrusions and associated turbulence, while fork crowns incorporate strategic cutouts to optimize airflow around the front wheel. These elements collectively contribute to a cohesive aerodynamic envelope.^[6]^[46] The philosophy originated in the early 2010s with the carbon C-Series road bikes, where features like integrated seat masts and aero-shrouded bottle mounts set the foundation for drag-minimizing designs. Performance benefits include claimed savings of 5-10 watts at 40 km/h speeds, positioning AeroLogic-equipped frames as UCI-approved options suitable for professional racing, including time trial models referenced in the Time Trial Bicycles section.^[45]

Reactive Pressure Molding

Reactive Pressure Molding (RPM) is a proprietary advanced molding technique developed by Litespeed Bicycles for the manufacture of high-performance carbon fiber frames. The process utilizes inflatable bladders inserted inside the frame tubes to apply internal pressure during the layup and curing stages, ensuring complete consolidation of the carbon prepreg material against the mold surfaces while minimizing excess resin and voids. This method allows for precise control over the internal geometry and wall thickness of the tubes, resulting in frames that are lighter and stiffer without compromising structural integrity.^[47] By combining internal bladder pressure with controlled heat in an oven or autoclave, RPM eliminates material waste on the inner surfaces of the tubes, achieving uniform wall thicknesses and avoiding inconsistencies associated with traditional external-pressure molding. This approach reduces the potential for weak points in heat-affected areas during curing, thereby enhancing overall durability and resistance to fatigue. The technique excels in forming complex junctions, such as integrated bottom bracket shells, where seamless bonding and optimal load distribution are essential for performance.^[48] Introduced by Litespeed in the early 2010s as an evolution of bladder molding, RPM has been refined for contemporary carbon models, supporting custom geometries with tolerances below 0.1mm for superior fit and ride quality. Compared to conventional carbon layup techniques, RPM produces frames that are approximately 15-20% lighter while delivering comparable or greater stiffness, establishing it as a core technology for consistency across Litespeed's composite frame lineup.^[49]
