Overview
This is an Ex-demo bike and therefore shows signs of use, please see pictures for details. The Turbine SL builds on the aerodynamic expertise of the Supersonica SLR, translating that high‑performance knowledge into a bike designed to make high speed a daily experience. It delivers exceptional versatility, accessibility, and impressive overall speed. The design of the Turbine SL prioritises clean, streamlined solutions and ease of riding, featuring full cable integration and the Deda Cronoevo Aerobar supplied as standard. The adjustable extensions, 6061 aluminium construction, and overall solidity allow riders to achieve an effective aerodynamic position immediately. Its frame structure is optimised to reduce air resistance: the wide-section down tube perfects airflow and shields the water bottle, while an asymmetrical fork, designed around the braking system, enhances precision and smoothness.
Spec may be subject to change due to availability Born For Triathlon Built for long-distance triathlon performance, the Turbine SL blends efficiency and comfort. It includes the 290 cm³ ATTK Profile Design Storage Case for carrying essentials without sacrificing aerodynamics. A dedicated seatpost and seat tube angle let the saddle sit around 2cm ahead of the bottom bracket, supporting an efficient triathlon position. 5 degrees seat angle suits the aggressive forward posture typical of time trials, enabling ideal use of tri-specific saddles and helping athletes maintain powerful, stable output over long efforts. Modern Components A fully electronic transmission keeps the bicycle clean and easy to manage. The removable front derailleur hanger allows for a quick switch between 1x and 2x setups, while the UDH compatibility ensures alignment with the latest standards.
With a tyre clearance of up to 32mm, it offers wide flexibility in tyre setups, providing greater comfort and control based on your preferences. Enhanced Fit - Maximum speed and stability Geometry on the Turbine SL is designed to combine speed and stability. A higher stack, compared to extreme time-trial setups, offers greater comfort over long distances, while an adjustable cockpit enables a precise fit, which is crucial for endurance riding. The lowered BB drop, alongside the Supersonica-derived frame design and components, provides an efficient, well-balanced riding position.
