Aero position on a road bike: how to ride faster without new equipment

In fact, changing position occasionally can relieve pressure on your hands and back, so you can save the aero posture for the stretches where it really counts.

TIP: For other ways to get quicker, see our guide on how to increase cycling speed.

Which road-bike hand position is most aerodynamic?

There’s no single fastest road bike position for everyone. Your build, flexibility and bike setup matter. Generally, a lower torso and narrower arms help, provided you don’t lose power or control.

The hoods are the rubber-covered tops of the brake levers. Aero hoods aren’t different equipment. Your hands stay put, but your elbows bend, your forearms become more horizontal and your chest comes down. With relaxed hoods, your arms are straighter and your torso higher. Moving into the drops with locked elbows isn’t automatically faster.

How to get lower without feeling cramped

Above: Bend your elbows and lower your torso while keeping a secure grip on the hoods.

Hold the hoods securely and bend your elbows slightly inward. Relax your shoulders, hinge from the hips and keep your eyes on the road. If your breathing feels restricted or braking becomes awkward, ease up.

Let your knees track naturally when pedalling. Forcing them together for a narrower outline can create other problems.

Film yourself side-on on an indoor trainer, comparing a relaxed position with a lower one. Look at your forearms, shoulders and neck. Sometimes what feels lower is simply a strained neck. The best position is one you can repeat, not one that looks brilliant in a photograph. Start with small adjustments. A few centimetres at the shoulders or a slightly more natural head angle can feel very different after an hour, and comfort is part of performance.

Try a controlled aero-position test

On one of ROUVY’s flatter routes, ride three five-minute efforts at the same comfortable power: relaxed hoods, bent-elbow aero hoods and the drops. Notice how your breathing, neck and shoulders feel. The trainer can’t tell you which position has less drag, but it’ll quickly show which ones you can actually maintain.

What riding with professionals taught me about descending

Above: Look through the bend and choose your speed before turning.

Riding with professionals and former professionals, I noticed how tidy they looked on fast descents. Elbows tucked in, knees not flaring out, upper bodies compact. Nothing exaggerated. They made themselves smaller in the wind whenever the road allowed.

On a straight descent, horizontal cranks keep the pedals level and give you a stable platform. Some riders believe they also cut through the air more cleanly, though a measurable benefit hasn’t been established. In corners, grip and pedal clearance matter more, often with the outside pedal down.

Smooth lines matter too. Look ahead, set your speed before a bend and avoid abrupt braking or steering. Never cross the centre line or take another road user’s space. A good line also means less unnecessary braking and accelerating afterwards, which can save effort over a long day. It should always come from anticipation, never from taking risks.

On safe, open straights, a lower torso with hands firmly in the drops keeps you compact and ready to brake. Sit higher when the road turns rough or technical. No aero saving is worth arriving at a corner faster than you can manage.

Which aero positions are unsafe or banned?

Don’t copy every cycling position you’ve seen in old race footage. The supertuck, with the rider sitting on the top tube, is prohibited in UCI road competition. So is resting forearms on standard road handlebars in UCI road races; approved time-trial extensions are different. See the UCI’s safety update.

Bent elbows with hands securely on the hoods are different. Clip-on aerobars are a separate issue, especially in groups.

If you can’t steer, brake or watch the road properly, don’t use the position. Control comes first.

How to train yourself to hold an aero position

Build it gradually. A position that feels easy for thirty seconds can become uncomfortable after twenty minutes, especially if your neck stiffens or power drops.

When I coach this, I watch the final minutes. Anyone can look tidy at the start; I want to see smooth pedalling and relaxed shoulders once fatigue arrives. I’d rather have ten controlled minutes than twenty spent fighting the handlebars.

Off the bike, dead bugs, side planks and glute bridges can help with trunk and pelvic control. Gentle hip and upper-back mobility may help too. See ROUVY’s core exercises for cyclists.

Indoor sessions let you practise without traffic, but they can’t replicate handling, gusts or road surfaces. Once comfortable, test the position outdoors somewhere quiet and safe. Build up from a few steady minutes rather than trying to sit low for an entire ride. You’ll soon learn when the posture feels useful and when sitting up makes more sense.

Can clothing, aero helmets and shaved legs help?

Yes, though I’d fix body position first. A close-fitting jersey is an easy start; flapping fabric creates drag. An aero road helmet may help airflow around your head, but the benefit depends on your posture and the design. Fit and ventilation still matter. A helmet that tests well on one rider won’t necessarily produce the same result on another, particularly if they hold their head differently.

Shaved legs? Oddly enough, there’s wind-tunnel evidence behind that familiar cycling habit too. In a BikeRadar test in Specialized’s wind tunnel, one rider saved around 48 seconds over a simulated 40 km. It’s an individual result, not a guarantee, but considerably cheaper than carbon wheels.

Should you change your stem, spacers or handlebar width?

First, work with the setup you’ve got. Removing spacers can lower your torso but also close your hip angle or load your hands. A longer stem or narrower bars aren’t automatically faster, and both may affect handling.

If you make a change, test one adjustment at a time. Numb hands, neck pain or poor handling are signals to reassess. ROUVY’s bike-fitting guide covers the contact points; consider a professional fit for bigger changes.

How to know if your new aero position is working

Check whether you can hold normal power without fighting the position. On the trainer, compare efforts at the same power, paying attention to breathing, stability and comfort. Useful feedback, yes, but not a drag measurement.

Out-and-back rides on a quiet, flat road can offer clues, although wind, traffic and temperature complicate comparisons. For reliable watt-saving figures, you’ll need proper aerodynamic testing.

For most riders, a repeatable position with easy breathing, smooth pedalling and sound handling is already progress. If a lower posture makes you lose meaningful power, any aerodynamic benefit could be cancelled out. That’s why I judge the whole rider, not just the silhouette.

Free speed is useful. So is arriving with energy left.

Aero riding isn’t about holding one dramatic shape all day. It’s knowing when to lower yourself, when to sit up and how to save energy without surrendering control. Practise until it becomes natural, then use it when the road allows. You might finish faster, with more left in your legs.
