RXL SL Carbon Aero Bars No Logo 3K Matte Adjustable Aero Bars 255mm, T800 carbon, 31.8mm clamp

The RXL SL Carbon Aero Bars are a lightweight, adjustable 31.8mm triathlon extender that adds aerodynamic armrests and extension bars to road or triathlon bikes for improved comfort and positioning.

Built from T800 carbon fiber and designed for 31.8mm clamps, these aero extensions let riders adopt a more aerodynamic, supported position for time trials, triathlons, and long-distance road rides. They combine low mass with damping properties, removable padded armrests, and a 15mm adjustable extension range so you can fine-tune reach and fit without swapping bars.

How do these bars improve comfort and endurance on long rides?

The RXL SL aero bars move your hands and forearms into a supported, forward position that reduces strain on the upper body. The included velcro-fixed sponge padding cushions pressure points and can be removed and washed for hygiene. Carbon construction gives slight elasticity to absorb road vibrations.

• Removable padded armrests reduce forearm pressure on long efforts
• Carbon fiber damping lowers transmitted vibration versus alloy
• Ergonomic shape encourages a relaxed, sustained aero tuck

Are these aero bars easy to fit and adjust on my bike?

Yes—these extensions clamp to standard 31.8mm handlebars and offer a 15mm adjustable extension length (240–255mm) so you can dial in reach. Installation requires at least 75mm of clear handlebar space and a torque setting around 4Nm for the clamp bolts. Use a hex key and tighten carefully to the recommended torque.

• Compatible with 31.8mm clamp diameter handlebars
• Adjustable extension length: 240–255mm for fine tuning
• Minimum 75mm handlebar mounting area required; tighten to 4Nm

How does carbon T800 compare to alloy for these aero bars?

T800 carbon fiber is lighter and has better vibration damping than aluminum alloy, which improves ride comfort and reduces overall bike weight. Carbon also allows cleaner, high-gloss finishes and stronger resistance to compression when clamped correctly. That said, carbon requires correct torque and careful installation to avoid damage.

• Approximately 320g weight—noticeably lighter than alloy alternatives
• Better anti-shock properties for a smoother feel
• Brighter finish and refined appearance for premium builds

What maintenance and care should I expect?

Armrest pads are secured with velcro so you can remove and wash them as needed. Inspect the clamp area periodically for correct torque and any surface damage. Avoid over-tightening and follow the 4Nm recommendation to preserve the carbon structure.

• Removable sponge padding for easy cleaning
• Regular torque checks prevent slippage and preserve carbon fibers
• Wipe with a damp cloth and mild soap; do not use harsh solvents

Who is this for: Cyclists who race triathlon or time trials, endurance riders wanting a more aerodynamic position, and bike builders seeking a lightweight, attractive upgrade for 31.8mm handlebars. These bars suit road bikes, triathlon bikes, and long-distance setups where lower weight, comfort, and fine adjustment matter.
