Video Description

Bike Fit Fundamentals: https://roadcyclingacademy.com/bike-fit-fundamentals/ In this video, experienced bike fitter Neill Stanbury explains why road bike sizing charts based purely on height often fail to put riders on the right bike. While most manufacturers list simple size recommendations (small, medium, large), real-world bike fit is far more complex than a height chart. We break down: Why bike sizing charts are hit and miss How leg length, torso length, arm length and hip mobility change ideal frame size Why two riders of the same height can need different frame sizes — or even different bike models The difference between aggressive race geometry vs endurance geometry Common mistakes riders make when buying an expensive new bike A real example of a rider who bought the "correct size" but couldn’t physically ride the bike What actually determines stack, reach, saddle height and handlebar drop The correct way to choose your next road bike frame Neill explains why flexibility, injury history, body proportions, weight distribution and riding posture matter far more than generic road bike sizing charts — and why a proper bike fit is the most reliable solution before buying your next bike. If you’re confused about: What size road bike you should ride Whether you should choose a race bike or endurance bike Why your current position feels uncomfortable How to avoid buying the wrong frame size This video will save you time, money, and frustration. 👉 Recommended next step: Bike Fit Fundamentals — a practical, step-by-step course to understand your own bike fit, positioning, and geometry before purchasing a new bike. https://roadcyclingacademy.com/bike-fit-fundamentals/ #cycling #bikefit
