Carbon Fibre TT Bike Handlebar with Integrated Clip-On Extension for Long Distance and Highway Riding, 31.8mm Clamp, Black Matt Finish, Available in 400/420/440mm Widths and S/M/L Sizes, 10° or 15° Angle Options
Carbon Fibre TT Bike Handlebar with Integrated Clip-On Extension for Long Distance Riding

Designed for cyclists who prioritise aerodynamic efficiency on long road or highway rides, this New Field Car TT timing handle combines a lightweight carbon fibre main bar with an integrated clip-on extension. The single-piece construction reduces weight and complexity while providing a stable platform for time trial, triathlon, or road racing. Weighing approximately 1000g and finished in black extinction (matt), the handlebar maintains a professional appearance and reduces glare. The 31.8mm clamp diameter fits standard road and TT stems, making it a straightforward upgrade for riders seeking better drag reduction without switching to a full aero cockpit.
Features and Construction

This handlebar is built as a single carbon fibre unit with separate clip-on extensions. The main bar width and TT reach can be selected individually to suit rider anthropometry and bike geometry.
Material and Build
Carbon fibre construction keeps the total weight around 1000g, offering a favourable stiffness-to-weight balance. The black extinction colour finish is matt and non-reflective, which helps reduce visual glare during sunny rides. All components are designed for integration with standard road or TT shifters and brake levers.
Size and Practical Fit
The main handle is offered in 400mm, 420mm, or 440mm centre-to-centre widths, measured at the ends. The clamp area is 31.8mm, matching the majority of modern stems. The TT bar angle is either 10° or 15°, and within each angle you can select a short (S), medium (M), or long (L) reach code. This system allows fine-tuning of arm position without separate adjustable extensions.
Uses and Placement

This handlebar is best suited to time trial bikes, triathlon bikes, and road bikes where an aero front end is desired. It can be used for training, sportives, and actual TT events.
Event or Professional Use
In timed events, the integrated TT bar with clip-on provides a repeatable, stable forearm position that can reduce frontal area. The available 10° or 15° angles let riders dial in their preferred arm angle for sustained effort. The carbon fibre construction transmits road feedback clearly without excessive vibration.
Everyday Home Use
For regular long-distance riders who train on open roads, the same aerodynamic benefits apply. The clip-on extension allows an alternative hand position during headwinds or steady-state sections, reducing fatigue on traditional drop bars. The black matt finish hides minor scuffs better than gloss.
Benefits and Buying Value

Choosing a one-piece integrated bar simplifies installation and removes compatibility concerns between different brands of base bars and extensions.
Reuse and Low Maintenance
Carbon fibre is corrosion-resistant and does not require paint or coating. The integrated design has fewer bolted joints than separate base-bar-plus-clip-on setups, reducing the number of torque checks needed. Always use carbon assembly paste on clamp surfaces as recommended by the manufacturer.
Why Choose This Product
With a 31.8mm clamp, it fits most modern stems. The three width and three reach options allow a tailored fit without buying multiple expensive components. The 1000g weight is competitive for an all-in-one TT bar. Choose between 10° or 15° depending on your flexibility and preferred forearm angle.
