3T Aura Pro / Ventus / Zefiro / Brezza TT Riser Kit – Adjustable Aero Spacers for Time Trial & Triathlon Bikes

High-performance riser kit by Dabrace™, engineered for 3T Aura Pro, Ventus, Zefiro and Brezza cockpits. Made from carbon fiber reinforced polymer (CFRP), with a strength-to-weight ratio of approx. 90 MPa/g/cm³. Lightweight, durable and fully adjustable thanks to its stackable spacer system – ideal for time trial and triathlon setups where comfort and aerodynamics must be perfectly balanced.

Product specifications

• Height range: 10 mm – no limit (choose total height)
• Includes: 4 extension bolts (possible to order more sets if needed)
• Custom combinations available – contact us for details
• Compatible with Dabrace™ Aero Bridges and BTA Hydration Systems

Stackable spacers

The spacers are stackable – configure the set by yourself to reach the exact height you need by using spacers of different sizes.
If you need 50 mm lift for both sides, order any combination that gives 50 mm (e.g. 5x10 mm or 2x20 mm + 1x10 mm).

Examples how to order (what height variants to add to the basket)

• Total height 30 mm (both sides):
  • 1x30 mm
  • 1x20 mm + 1x10 mm
  • 3x10 mm
• Total height 60 mm (both sides):
  • 1x60 mm
  • 1x30 mm + 1x20 mm + 1x10 mm
  • 3x20 mm
  • 2x20 mm + 2x10 mm

Aero Bridge (stability support)

For setups of 50 mm or higher we recommend using an Aero Bridge. It significantly increases cockpit stability. Please note: installing the Aero Bridge raises the entire aerobar system by an additional 10 mm. The Aero Bridge is also fully compatible with our proprietary BTA hydration system, allowing seamless integration of stability and hydration solutions.

This modular system allows maximum flexibility: simply combine different spacer sizes to achieve your preferred stack height.
