Best Clip-On Aero Bars for Triathlon and Road Bikes
What to Look For
Clip-on aero bars transform your road bike into a time trial machine without buying a new bike. For triathlon — where drafting is prohibited and aerodynamic position matters enormously — clip-ons can save 5-10% in effort or several minutes over 40km. The right set balances aerodynamics, comfort, and adjustability for your body and event distance.
Key Features to Consider
- Adjustability — Width, reach, and height adjustment allow you to dial in position across different arm lengths and bike geometries
- Arm pad design — Wider, softer pads improve comfort on longer rides; narrow pads reduce drag for race-day TT efforts
- Extension shape — S-bend or J-bend extensions place your hands in a more relaxed position; straight extensions are most aerodynamic for pure speed
- Weight — Race-day bars can be as light as 300g; heavier aluminium training bars trade weight for durability and lower cost
Our Top Picks
Best Overall: Profile Design Flip/Ergo/50a Aerobar
The Profile Design Flip/Ergo is the most popular entry into the aero bar world for good reason. It features adjustable-width armrests, ergonomic pads, and a flip bracket that lets you access your drop bars at any time without removing the extensions. The S-bend 50a extensions provide excellent comfort for sprint, Olympic, and 70.3 distances on a road bike.
Best Value: Redshift Quick-Release Aero Bars
The Redshift Sports Quick-Release bars solve the most common triathlete problem: you do not want aero bars for your evening club ride or your hilly Sunday long run. The patented quick-release system lets you attach and remove the bars without tools in under 10 seconds. Aerodynamics and arm comfort are solid for the price, making these an excellent choice if you share one bike between triathlon and non-draft events.
Best for Racing: Profile Design Airstryke V2 Clip-On Aerobar
The Airstryke V2 steps up with more aerodynamic arm pads, better reach and stack adjustability, and a cleaner integration with most road and triathlon bikes. The adjustable design suits athletes who want a precisely tuned fit, and the lighter construction makes it a solid race-day upgrade. A popular choice for club-level time triallists and Olympic-distance athletes who want more adjustability than the Flip/Ergo provides.
Buying Tips
- Measure your handlebar diameter before buying — most clip-ons fit 31.8mm or 26mm bars, but some older bikes differ
- Set up your aero position 4-6 weeks before your target race to allow your body to adapt to the new position
- Draft-legal races do not allow aero bars — check your race rules before attaching them for Olympic or sprint events
Care and Maintenance
Wipe down aero bars after every session, particularly after open road rides in wet conditions. Check clamp bolts monthly as road vibration can loosen them over time. Inspect arm pads for wear — replacement pads are available separately from most manufacturers.
