Profile Design aerobar bracket riser kit, Black, 50mm lift for T+ Carbon/T+ Aluminum — raises armrests for comfort

Profile Design's Aerobar Bracket Riser Kit (50mm, black) raises your existing Profile Design armrests and extensions for a more comfortable, efficient fit on time-trial and triathlon handlebars.

If your torso length, shoulder width, or riding posture requires the bars to sit higher than stock, this riser kit gives a clean, reliable way to increase extension and pad height without swapping stems or bars. Designed specifically for compatibility with Profile Design T+ Carbon, T+ Aluminum and Sonic Ergo 35a systems, the kit replaces the bracket stack to lift both armrests and extensions together so your wrist angle and reach remain consistent. It’s a straightforward mechanical solution when you want to fine-tune position for power, comfort, or aerodynamics.

How much height does the 50mm riser add and how does it affect fit?

The 50mm bracket riser increases the vertical position of the armrests and extensions by 50 millimeters from the original bracket mounting plane, giving substantial clearance for riders who need a higher cockpit. Increasing height shifts torso angle and can relieve shoulder strain or enable a more efficient breathing posture when combined with proper bike fit adjustments. Because the kit raises both pads and extensions as one unit, hand and wrist alignment stay predictable.

• Adds a fixed 50mm vertical lift for the compatible armrest systems.
• Maintains pad-to-extension geometry to protect wrist comfort.
• Works with existing clamps and bolts included for the kit size.
• Not intended for Carbon Style handlebars—check compatibility first.

Will this riser kit work with my T+ Carbon or T+ Aluminum aerobars?

Yes—this riser is engineered to interface directly with Profile Design T+ Carbon, T+ Aluminum, and Sonic Ergo 35a armrest platforms. The kit includes the specific riser pieces and hardware sized for the 50mm upgrade so installation swaps into the existing clamp assembly. Always confirm your current armrest model before purchasing to avoid mismatched parts.

• Compatible models: T+ Carbon series, T+ Aluminum series, Sonic Ergo 35a.
• Includes risers and bolts tailored to the 50mm configuration.
• Simple replacement of the bracket stack—no special tools beyond standard hex wrenches.
• Do not use with Carbon Style systems; verify model labeling on your bars.

How difficult is installation and what tools are required?

Installation is straightforward for anyone comfortable with basic bike maintenance: remove the existing bracket stack, install the riser pieces, torque the supplied bolts, and double-check alignment. No frame drilling or permanent modification is needed. If you’re unsure, a local bike shop can fit it quickly during a standard cockpit adjustment session.

• Typical tools: hex keys/Allen wrenches and a torque wrench for proper bolt tightness.
• Installation swaps the bracket assembly—takes 15–30 minutes for an experienced mechanic.
• Includes matching hardware sized for the 50mm riser to ensure secure mounting.
• Recommended: verify final clearance for cables and accessories after fitting.

Will raising the bars change my handling or comfort on longer rides?

Raising the armrests alters your body geometry, which can improve shoulder and neck comfort for many riders by reducing extreme torso flex. It can also change weight distribution and steering feel slightly, so plan a controlled test ride and make small iterative changes. Pairing the riser with a professional bike fit helps you balance aerodynamics, power position, and comfort for endurance efforts.

• May reduce shoulder strain by opening the torso angle.
• Can influence weight over the front wheel—test carefully after installation.
• Best used as part of a comprehensive fit adjustment rather than a standalone fix.
• Provides a predictable, modular way to try taller positions without swapping bars.

Who this is for: cyclists and triathletes using Profile Design T+ Carbon, T+ Aluminum, or Sonic Ergo 35a aerobars who need a substantial, reliable vertical adjustment without replacing their entire cockpit. Ideal for riders with longer torsos, those seeking reduced shoulder compression, or athletes experimenting with position changes for endurance or time-trial performance. Avoid this kit if your setup uses Carbon Style armrests; otherwise it’s a practical, bolt-on way to tailor fit and comfort.
