Profile Design Ergo Injected Armrest Kit — Black, 10mm Pads, 145g Lightweight, Fits Legacy Aero Bars

The Profile Design Ergo Injected Armrest Kit is a lightweight, ergonomically shaped armrest set designed to cradle your elbows and offer broad adjustability for aero bar setups.

Profile Design built the Ergo as the foundation of a new range focused on fit and rider comfort. Its gently curved top surface cups the elbow for stable contact while allowing maneuverability and control. Constructed from injected nylon reinforced with glass fiber and fitted with 10mm pad inserts, the pair weighs just 145 grams and fits many current and legacy aero bar systems.

How does the Ergo shape improve comfort during rides?

The Ergo’s smoothly contoured profile spreads pressure across the elbow instead of concentrating it at a point, which helps reduce hotspots and improves sustained stability. The 10mm pads provide a soft interface without excessive bulk, so your forearms sit comfortably in a natural position.

• Curved top designed to cradle the elbow and maintain contact.
• 10mm pad layer for cushioning with low compression.
• Wide contact area for reduced pressure points during long efforts.

Will this armrest kit fit my aero bars and how adjustable is it?

The Ergo uses a versatile bolt pattern that allows 48 different mounting positions, enabling fore-aft, lateral, and rotational adjustments to fine-tune your arm position. It’s compatible with current aero bars and older models that used f-19, f-22, f-35, or f-40 armrests, making it easy to upgrade or replace existing pads.

• 48 possible configurations from the bolt pattern for precise fit.
• Compatible with current aero bars and legacy f-19/f-22/f-35/f-40 mountings.
• Simple hardware arrangement for predictable adjustment steps.

What are the construction and weight characteristics?

The Ergo armrests are molded from injected nylon reinforced with glass fiber for a balance of stiffness and resilience. The combination keeps weight low—145 grams per pair—while maintaining a supportive platform that resists deformation under load.

• Injected nylon with glass fiber for durability and controlled flex.
• Lightweight pair weight: 145 g, suitable for performance setups.
• Matte black finish for a low-profile look that matches most cockpit components.

How do I maintain or replace the pads over time?

The pads on the Ergo are 10mm model inserts designed for straightforward replacement when worn. Because the armrest is a modular component, swapping pads or cleaning the surfaces is a quick process that doesn’t require specialized tools.

• Removable 10mm pads for easy replacement or cleaning.
• Durable shell resists wear so pads are the primary consumable part.
• Accessible mounting points to speed-up maintenance or upgrades.

Who is this for? The Profile Design Ergo Injected Armrest Kit is aimed at cyclists seeking a lightweight, adjustable elbow platform for time trial, triathlon, or aero-focused training. It suits riders who want a balance of comfort and control, need compatibility with a range of aero bars (including older f-series mounts), and prefer a low-profile matte-black aesthetic. Choose the Ergo if you want an ergonomic armrest that supports fine-tuned positioning and straightforward upkeep without adding significant weight to your cockpit.
