The Altias Fusion Frameset is an Olympic-spec track frame engineered for strength, stiffness, and aerodynamics. Wind tunnel validation shows a saving of up to 24W over comparable Olympic-tier framesets. Enhanced with a system-led development philosophy, the Fusion is the centre of a performance optimisation package, yet still allows for universal component integration.

Engineered for Speed

Altias Fusion is engineered for Olympic-level speed. Wind-tunnel validation shows up to 24W less power required than comparable Olympic-tier framesets for a 9.5s flying 200m time trial. The frame is built around peak forces measured from Olympic-level sprint data. The stiffness is tuned to resist the deflection during gate starts, accelerations, and high-speed efforts, holding a line at 70+ km/h. An optimised carbon layup removes non-working material and aligns key fibres to load paths, delivering a responsive feel without the dead, over-built sensation.

Innovative Geometry

The Altias Fusion treats the rider as part of the bike, not just sitting on top. Its long, low sprint stance delivers 'railed' high-speed characteristics and precise control for line changes in the bunch.

Sizes L and XL push out towards UCI reach limits for a long position, while S and M keep the same sprint posture through proportionate stack and reach. A lower bottom bracket, built around modern shorter cranks, drops the centre of mass and reduces frontal area.

Universal and Future-Proofed

The Altias Fusion is built to slot into your programme today to continue improving tomorrow. A 1⅛″ steerer accepts any standard stem, the T47 bottom bracket fits widely available cranksets. Front and rear dropouts allow any standard wheels to bolt straight on.

The full Altias system unlocks the greatest gains. A frame-fork interface with deliberate design features future upgradeable setups. The frame stays constant, you tune the front end and components for athlete or event specific optimisation. Backed by Velobike Innovation's ongoing collaboration with national teams and Olympic athletes, the platform stays current through the Olympic cycle and beyond.

The Fusion Frameset shows a consistent advantage over comparable Olympic-tier sprint framesets from the previous Olympic cycle.

No stem/spacer combinations fall within 10 mm of your target in both reach and height.

Results within ±10 mm are ranked by fit accuracy. Where fit is similar, fewer spacers are preferred. Fewer spacers generally improves stiffness.
