Do aerodynamics really matter?

If you’re a casual swimmer, occasionally taking part in open water swims, not having shaved legs or a brand-new skin fitting costume isn’t going to affect your time as much as improving your technique and power. However, for professional swimmers who have perfected their technique and who are at peak physical strength, having those fitted items and shaved legs may make the split-second difference between coming second and beating the world record.

But does aerodynamics on the bike, including gear, fitting, and position, really change your time enough for you to worry about these aspects of cycling?

When it comes to cycling, as with swimming, the best way to improve your time is to get stronger. But you are also always pushing against the air, so improving your aerodynamics can help you to improve your times – though not as much improving your strength. Here are some ways you can improve your aerodynamics on the bike:

• You don’t need all the gear. While an aero helmet, aero bars, shoe covers, and a skin suit make you look ultra-slick and ready to ride, these don’t actually make as much difference to your aerodynamics as your ride position. In addition, ride gear can be a lot more expensive than your standard gear and for a weekend warrior – even a dedicated one – the gains aren’t worth the gear.
• Build your core strength. While you don’t necessarily need aero bars or tri bars to drop your torso down into the position you see pros racing in, it does help. It’s possible to lower your torso even on standard mountain bike handlebars, but the most important aspect of this factor is to know how low you can go without hurting your back. Building core strength will help you lower your body to become more aerodynamic without hurting yourself.
• Improve your flexibility. As soon as you bend yourself over, your hips, glutes, and hamstrings have to be more flexible to stretch further and to keep the power in your legs. Working on touching your toes from a standing position can help to improve this. In general, attending a few Pilates classes will improve your cycling.
• Make sure you’re comfortable. Especially for casual riders, comfort and power should be the main focus over aerodynamics. You don’t want to come off a 40 km ride feeling like you were crushed.

The best strategy is to get your bike fitted to you for the perfect angles and the perfect balance between power, aerodynamics, and comfort.
