When it comes to triathlon and time trialing, every second counts, and one of the most effective ways to shave time off your bike leg is by improving your aerodynamics. Reducing drag can lead to significant gains, and the best part is, you don’t have to be a pro or spend a fortune to do it. Here are some easy, cost-effective ways to gain an aero advantage on your triathlon bike.
1. Perfect Your Bike Fit
A proper bike fit is crucial for both comfort and aerodynamics. A well-fitted bike allows you to maintain an aero position for longer periods without discomfort. Even slight adjustments in saddle height, handlebar position, or reach can significantly reduce your frontal area, which is key to cutting through the wind. It’s worth investing in a professional bike fit, as it can be the cheapest way to prevent injuries and improve overall performance.
2. Get Low and Narrow
The position of your body on the bike plays a massive role in aerodynamics. The lower and more compact you can make your body, the less wind resistance you’ll face. This doesn’t mean you need to hunch over or sacrifice comfort. Small changes, like lowering your handlebars slightly or tucking your elbows in closer to your body, can reduce drag. Practice holding this position during training to ensure you can maintain it during the race. Most triathletes have their chest in the wind or ride the horns due to a variety of reasons, no bike fit, comfort, but this is sacrificing time.
3. Optimize Your Helmet
Your helmet is one of the most important pieces of aerodynamics. An aero helmet, designed to minimize drag, can provide a significant advantage. The key is to choose one that suits your riding position and speed. If you often ride with your head up, a helmet with a tail might be beneficial, while a shorter-tail or even tail-less helmet might be better for those who move their head frequently. Additionally, make sure your helmet fits snugly and is aligned properly with your back when you’re in an aero position. Some helmets will slow you down, so trial and error for what works for your position is key.
4. Dress for Success
Your suit can also have a significant impact on your aerodynamics. Loose, flapping clothing creates drag, so opting for a tight-fitting tri suit can help you cut through the air more efficiently. Many modern tri suits are designed with aerodynamic materials that reduce drag, especially on the arms and shoulders. Even simple things like tucking in the zipper pull or choosing a suit without pockets on the back can make a difference. Believe it or not, your shoe choice can offer marginal gains in reducing resistance!
5. Upgrade Your Wheels
Not the cheapest option, upgrading to aero, or deeper, wheels can provide one of the biggest gains in speed. Deep-section wheels reduce the drag caused by your wheels spinning through the air. If new wheels are outside your budget, even a set of aero wheel covers can help improve aerodynamics at a fraction of the cost. Another tip is to ensure your tires are properly inflated, to the road, weather, and temprature, and that you choose tires with a lower rolling resistance, which can also improve speed.
6. Clean Up Your Bike
A cluttered bike is a slow bike. Clean up your cockpit by minimizing the number of items attached to your handlebars and frame. Consider using an aero water bottle or a hydration system that fits between your arms in the aero position. Keep cables tidy and close to the frame, and remove any unnecessary accessories. Even small things like using shorter bolts or taping down exposed cables can help reduce drag. Electrical tape is my best friend!
7. Practice Riding in Aero Position - OUTSIDE
No matter how aerodynamic your gear is, it won’t make much of a difference if you can’t stay in the pads. Spend time training in your aero position to build the necessary strength and flexibility and pracrice head discipline. Start with short intervals in the aero position and gradually increase the time you spend in it. The more comfortable and stable you are in this position, the more you’ll benefit from all your aero improvements.
8. Maintain Your Bike
A well-maintained bike is a fast bike. Regularly clean and lubricate your chain, keep your tires inflated, and ensure your drivetrain is in good condition. A smooth-running bike not only feels better to ride but also reduces rolling resistance, helping you maintain higher speeds with less effort. Additionally, a clean bike creates less drag than one covered in grime and dirt.
Gaining an aero advantage on your triathlon bike doesn’t have to be expensive or complicated. With a few simple adjustments and investments, you can significantly reduce drag and increase your speed. Whether it’s perfecting your bike fit, optimizing your gear, or practicing your aero position, these easy steps can help you shave valuable seconds off your bike leg and improve your overall triathlon performance.
