Profile Design Aerobar Bracket Riser Kit 60mm — Black, 31.8mm Clamp, Adjustable 20–70mm

The Profile Design Aerobar Bracket Riser Kit raises compatible aero bars between 20mm and 70mm to deliver a precise, customized armrest height.

If your clip-on aerobars sit too low or too high for your comfort, this riser kit provides a simple, tool-friendly way to fine-tune stack height without changing stems or bars. Built for Profile Design T+ Carbon, T+ Aluminum and Sonic Ergo 35a systems, the kit keeps your cockpit tidy while increasing control, comfort and aerodynamic posture options for training and race days.

How does this riser kit change my riding position?

The riser changes the vertical position of your aerobar clamps, so your forearms and shoulders align more comfortably with your desired aero tuck. Small incremental increases let you dial in spine angle and reach while keeping the original bar geometry intact.

• Available spacings: 20mm, 30mm, 40mm, 50mm, 60mm, 70mm for precise tuning
• Clamp diameter: 31.8mm to match standard aerobars and extensions
• Adjusts height without altering extension reach or pad placement

Will this fit my Profile Design aerobars and extensions?

Yes — the riser is engineered to work with Profile Design’s T+ Carbon, T+ Aluminum and Sonic Ergo 35a aerobar families. It integrates directly with the bracket/clamp interface used by these models so installation is straightforward and secure.

• Compatible models: T+ Carbon, T+ Aluminum, Sonic Ergo 35a
• Designed for the same clamp profile used across Profile Design aero product lines
• Black finish matches common cockpit components for a clean look

How easy is installation and maintenance?

Installation is quick with standard hex tools; the kit slides into the existing bracket stack and is secured by the original fasteners. Routine checks for snugness and corrosion prevention are all that’s needed to keep the riser functioning reliably.

• Simple install with common hex keys — no specialty tools required
• Fits the 31.8mm clamp interface used on many aerobars
• Limited 2-year manufacturer warranty for part defects

Does raising the bars affect aerodynamics or control?

Raising bar height can slightly change aerodynamic profile, but the goal is to find the best balance between comfort and speed. Increasing stack lets riders hold an efficient position longer, often improving sustained power output and steering control for longer efforts.

• Height options from 20mm to 70mm let you prioritize comfort or aero gains
• Maintains original bar alignment and clamp stability for safe handling
• Black finish reduces visible reflections and keeps a unified cockpit aesthetic

Who is this for: Triathletes and time-trial cyclists who use Profile Design T+ Carbon, T+ Aluminum or Sonic Ergo 35a aerobars and need straightforward vertical adjustment without replacing bars or stems. It's ideal if you want incremental height options (20–70mm), a standard 31.8mm clamp fit, and a durable black component covered by a limited 2-year warranty. Whether optimizing comfort for longer rides or tweaking position for faster, more sustainable efforts, this riser kit gives a clean, reversible way to refine your cockpit setup.
