Best Triathlon Aero Bars and Extensions in 2026
Aero bars and handlebar extensions can transform your triathlon bike position, slashing wind resistance and delivering faster bike splits without buying a new bike. Whether you’re fitting clip-ons to a road bike for your first sprint or upgrading the integrated extensions on a dedicated TT bike, choosing the right setup makes a real difference to both comfort and aerodynamics.
Key Features to Consider
- Reach and stack adjustment: The ability to move the pads forward, back, up and down is essential for dialling in a position that’s both aerodynamic and sustainable across a long race. Look for multiple adjustment points rather than a single fixed position.
- Extension shape: Ski-bend extensions (curving upward at the tip) suit most triathletes, allowing you to shift your hand position slightly during a long bike leg. Straight extensions are more aggressive and better suited to short-course racing.
- Material: Aluminium extensions are durable and affordable. Carbon extensions save weight and can dampen road vibration, which matters on rough race courses or long-distance events.
- Pad width: Shoulder-width pads allow a more relaxed position suited to longer events. Narrower pad spacing creates a more aerodynamic silhouette for short-course racing.
Our Top Picks
Best Budget: Giant Contact Ski-Type Bar Extensions 22.2mm (£34.99)
An outstanding entry-level option for triathletes adding aero bars to a road bike for the first time. The ski-bend shape suits most riders, the 22.2mm diameter clips onto standard bar-end mounts without adapters, and the aluminium construction is genuinely durable. For anyone doing their first sprint or Olympic triathlon, this is the most cost-effective way to get into an aero position without overspending on your first setup.
Best Mid-Range: Deda Superzero TT Extensions (£207.99)
The Deda Superzero sits in the premium-aluminium bracket — machined to tighter tolerances than budget options, with multiple reach positions and a refined ski-bend profile that works well for athletes in both short and long-course events. If you’ve committed to triathlon for more than one season and want extensions that will grow with your position refinements, the Deda Superzero is a worthwhile investment over budget alternatives.
Best Premium: Vision Metron TFE WA Carbon Extensions (£589.99)
For athletes racing long course and serious about aerodynamics, the Vision Metron TFE WA Carbon extensions are a benchmark product. Full carbon construction saves significant weight over aluminium alternatives, and the wide-angle (WA) design allows a wider hand position that many athletes find more comfortable across 90+ km bike legs. The carbon layup also absorbs road vibration more effectively, which matters on poorly surfaced race courses. A serious upgrade for dedicated triathlon setups.
Buying Tips
- Always get a bike fit before finalising your extension position. An aggressive extension setup that looks fast can actually slow you down if it compromises your breathing or puts excess stress on your lower back over long distances.
- Check bar-end compatibility before ordering — some road bikes have proprietary bar-end diameters that require adapters for standard 22.2mm extensions.
- Train in your aero position regularly before race day. An hour in aero on the turbo trainer twice a week will dramatically improve your comfort during the race itself.
Care and Maintenance
Check extension bolts for tightness before every race — vibration can gradually loosen the clamp bolts, which is both a performance and safety issue. Wipe down pads regularly; old foam pads can be replaced cheaply from most bike shops. Carbon extensions should be inspected for cracks after any crash or impact before returning to use.
