Profile Design Legacy II Aerobars
Ergonomics and durability come together in Profile Design’s Legacy II Aerobars. Forged 6061-T6 aluminum construction underpins a design that combines Venturi-style armrests with multiple hand positions. The width and armrest orientation are adjustable, enabling a snug, secure fit for a wide range of road bikes. The result is reduced fatigue on long rides and improved aerodynamics for triathlons and time trials.
Key features include adjustable width and rotational arms, which help tailor the stance to different riders or bike geometries. Aimed at triathlons and long-distance rides, these aerobars are designed to maximize speed with lower drag. While aluminum adds strength, users should verify compatibility with their stem and handlebar setup to ensure clean cable routing and proper clamp alignment.
RXL SL Adjustable TT Bar
This carbon fiber TT bar from RXL SL emphasizes lightness and stiffness. The bar uses a 31.8mm clamp and a 255mm length with a 15mm adjustable extension, making it easy to fine-tune reach. A sponge pad on the arms enhances comfort, and the padding is removable for washing. Installation guidance emphasizes correct torque (4 Nm) and the use of proper fasteners to minimize slippage, ensuring a stable aero position during long rides.
Design notes highlight the TT rest’s angle versatility and overall weight around 300g, which helps preserve the bike’s overall weight. Pros include a straightforward quick setup and significant aero gains. Consider your clamp compatibility and whether a 360mm option would better suit your frame geometry for a more aggressive stance.
BBB AeroBars BHB-60
The BBB AeroMax two-piece aluminum aero bar features long J-bend bars and multi-adjustable arm pads to optimize aerodynamics. A 350mm J-bend extension length contributes to a more streamlined profile, reducing drag on flat or rolling sections of a triathlon course. Foam padding provides comfort during high-mileage rides, and EVA padding on the bars helps minimize road buzz against the forearms.
Ideal for riders seeking a two-piece setup with a straightforward, adjustable configuration. Check compatibility with your frame’s head tube geometry and ensure the extension length aligns with your preferred aero position. The combination of aluminum construction and padding balances durability with comfort for longer events.
BBB Aero Bars BHB-59
BBB’s BHB-59 aero bars offer a 35mm rise with a two-piece aluminum construction designed for road bikes seeking an elevated aero position. AeroComfort padding and EVA foam sleeves around the steer tube enhance comfort during extended efforts. The setup aims to strike a balance between an aggressive forward position and rider comfort, making it a sensible choice for triathlons or long-distance racing where wind resistance matters.
Consider the 35mm rise if you want a higher reach to clear aerobar arms and elbows, or if you prefer a slightly more upright posture for endurance segments. Ensure the pad height and armrest width suit your torso length and shoulder width to avoid shoulder strain during long events.
REDSHIFT Quick-Release Clip-On Aero Bars
The REDSHIFT quick-release aero bars offer a practical transition between road and aero positions. The clip-on mechanism allows removal or reattachment with minimal tools, enabling riders to switch as terrain or course requirements change. This feature is particularly beneficial for mixed courses or multi-day events where different segments demand different ergonomic setups.
Key advantages include the on-the-fly adjustability and ease of installation. The design emphasizes quick, tool-free changes while maintaining a secure, repeatable fit. Users should verify clamp compatibility and confirm that the quick-release interface does not interfere with existing cables or brake levers on their bike.
SATORI Bike Bullhorn Handlebar
This bullhorn style bar from Satori is crafted from Alloy-6061, delivering strength with lightness for fixie and road setups. Its ergonomic curve and 20mm diameter support a comfortable wrist position, potentially reducing fatigue during long efforts. Compatibility with fixed-gear brakes or standard brake levers makes it versatile for various builds, though its direct fit should be verified with your brake system to ensure proper braking leverage and control.
Key considerations include the clamp size and whether the bullhorn form will integrate cleanly with your chosen aero system. While not a traditional aero bar, its shape can suit riders prioritizing a distinctive aero posture without a full aero extension.
RXL SL Carbon Aero Bar Extenders
RXL SL’s carbon aero bar extenders emphasize a flat ski bend extension design for improved aerodynamics and a longer grip angle. Constructed from T700 carbon fiber, these extenders are lightweight and compatible with 31.8mm clamps. The 360mm length and 30°/40°/50° angle options support a versatile aero stance, while sponge padding provides arm comfort during extended segments. Proper installation torque (4 Nm) is recommended to prevent slippage and ensure stability in aggressive riding positions.
Consider the extender’s alignment with your frame geometry and handlebar width. Carbon fiber offers stiffness with vibration damping, but proper torque and secure mounting are essential to preserve steering feel and safety at high speeds.
RXL SL Aero Carbon Road Handlebars
These carbon road handlebars by RXL SL focus on a lightweight, stiff, and low-noise design suitable for triathlon setups. With 31.8mm clamps and multiple length options (400/420/440mm), they offer a conventional drop bar experience with added aerodynamics through carbon fiber. The product includes recommended installation torque (4 Nm) and emphasizes proper alignment with the brake system to ensure safe and precise braking performance in competitive scenarios.
Key considerations include the potential weight savings of carbon, the need for compatible brake levers, and whether you require a deeper drop for your riding style. Carbon bars can offer superior stiffness and damper characteristics but can be more vulnerable to impact damage than aluminum options.
Buying Guide: Key Purchase Considerations
- Material and weight: Carbon fiber bars are lighter and stiffer but can be pricier and more damage-prone than aluminum. Balance weight savings with road durability for your riding style and course conditions.
- Clamp compatibility: Confirm your stem and handlebar clamp diameters (commonly 31.8mm). Mismatches can lead to poor alignment or safety concerns.
- Adjustability: Look for adjustable armrests, pad height, and extension length. A customizable setup helps optimize aerodynamics and comfort across varied race profiles.
- Padding and comfort: Foam or EVA padding on aero pads improves long-ride comfort. Ensure pads are removable for cleaning or replacement.
- Installation torque: Follow manufacturer-recommended torque (often around 4 Nm). Improper torque can cause slippage or structural failure under load.
- Weight distribution and balance: Aero bars affect bike handling. Ensure the setup maintains proper steering response and frame geometry alignment.
- Compatibility with accessories: If using quick-release or clip-on systems, verify interference with cables, brakes, and digital sensors on your bike.
- Intended use: For triathlons, prioritize a position that reduces drag while preserving control on descents and irregular roads. For time trials or longer distances, ensure comfort is not sacrificed for marginal aerodynamic gains.
- Maintenance: Carbon components require careful inspection for cracks after heavy use or crashes. Aluminum components are generally more forgiving in impacts but can bend or deform under extreme loads.
Riders should assess their bike’s geometry, leg length, and shoulder width when choosing aero bars. A trial-fit, if possible, helps prevent shoulder or neck strain and ensures the aerobar setup complements the rider’s natural posture. For competitive triathlons, a professional bike fit can translate to meaningful gains in efficiency and comfort.
