When you want to ride faster or further, it is easy to assume that the newest bike or latest gear will make the biggest difference. In reality, cycling performance investments deliver very different returns depending on your current setup, training and goals. This guide compares the likely impact and cost of aero testing, bike fit, nutrition, coaching and equipment so you can prioritise where to spend.
Aerodynamic testing
Performance improvement: 5-20%
Aerodynamic testing is a game-changer, especially for time trialists and triathletes. By optimising your position and gear, you can significantly reduce drag, translating to substantial speed gains without additional effort. Expect a 5-20% performance improvement with professional aerodynamic testing, deeding on how optimised your existing position is.
Cost: $500-$1,500
Bike fit
Performance improvement: 5-15%
A professional bike fit ensures that your bike setup is tailored to your body, enhancing comfort, efficiency, and power output. Again, depending on your current position, this can lead to a 5-15% improvement in performance, making it one of the most cost-effective upgrades.
Cost: $150-$1000
Nutrition
Performance improvement: 5-10%
Proper nutrition is crucial for endurance and recovery. Optimising your diet and hydration can lead to a 5-10% improvement in performance. This includes everything from daily nutrition to race-day fueling strategies.
Cost: Variable, but generally $50-$200 per month
Coaching
Performance improvement: 10-20%
Investing in a coach can yield significant performance gains. A coach provides tailored coach led plans, feedback, and accountability, leading to a 10-20% improvement in your performance over time. Of course I would say that, but I genuinely believe it’s one of the best cycling performance investments.
Cost: Variable, but between $150-$800 per month
Wheels
Performance improvement: 2-5%
Upgrading to a high-quality, aerodynamic wheelset can make you faster by reducing rolling resistance and improving aerodynamics. Expect a 2-5% performance gain from this upgrade.
Cost: $800-$2,500
New bike
Performance improvement: 1-5%
While a new bike can be exciting, the performance gains are often less significant than other investments unless your current bike is outdated. You can expect a 1-5% improvement, primarily from improved aerodynamics and reduced weight.
Cost: $2,000-$15,000
Aero helmet
Performance improvement: 1-3%
An aero helmet can provide a small but noticeable improvement in speed by reducing drag. This is a cost-effective way to gain a 1-3% performance boost.
Cost: $150-$400
Power meter
Performance improvement: 5-10%
Using a power meter allows you to train more effectively by targeting specific power zones. This can lead to a 5-10% improvement in performance as you can fine-tune your training and pacing strategies.
Cost: $400-$1,200
Clothing and skinsuits
Performance improvement: 1-4%
Investing in high-quality, aerodynamic clothing and skinsuits can reduce drag and improve comfort. This can lead to a 1-4% improvement in performance.
Cost: $100-$1000
Tires and tubes
Performance improvement: 1-3%
High-quality tires and latex tubes can reduce rolling resistance, providing a small but cost-effective performance gain of 1-3%.
Cost: $50-$200
Cycling performance investments
| Investment | Performance improvement | Cost range |
|---|---|---|
| Aerodynamic testing | 5-20% | $500-$1,500 |
| Bike fit | 5-15% | $150-$1,000 |
| Nutrition | 5-10% | $50-$500/month |
| Coaching | 10-20% | $150-$800/month |
| Wheels | 2-5% | $800-$2,500 |
| New bike | 1-5% | $2,000-$15,000 |
| Aero helmet | 1-3% | $150-$400 |
| Power meter | 5-10% | $400-$1,200 |
| Clothing/skinsuits | 1-4% | $100-$1,000 |
| Tires and tubes | 1-3% | $50-$200 |
Summary
The best value is usually found by addressing the factors that limit your performance most, rather than simply buying the most expensive upgrade. If you would like help deciding what to prioritise for your goals, Book a Free Consultation.
