Summary

TLDRIn this insightful video, physiotherapist and bike fitting expert Phil Burt discusses common concerns cyclists have about bike sizing. He highlights key signs that indicate a potential sizing issue, such as stem length and handlebar width. Burt emphasizes the importance of optimizing contact points, starting with saddle height and fore-aft position, to enhance comfort and performance. He encourages riders to utilize online fitting tools while considering individual body proportions, reassuring them that many fitting issues can be resolved with adjustments rather than purchasing a new bike. This informative session is a must-watch for any cyclist looking to improve their riding experience.

Takeaways

  • 😀 A common sign of an improperly sized bike is using a very short stem (less than 90mm) or an inverted stem.
  • 🚴‍♂️ Many riders mistake saddle height and setback issues for having the wrong bike size, leading to discomfort and incorrect perceptions of bike fit.
  • 📏 The width of the handlebars should align with the rider's shoulder width; handlebars that are too wide can affect reach and comfort.
  • 🔧 Start optimizing bike fit by adjusting the saddle height, then move to the fore-aft position, and finally address handlebar and stem length.
  • 🛠️ Crank length can significantly impact comfort and performance, especially for riders with shorter legs or different body proportions.
  • 📐 Stack height is crucial; a bike with too low of a stack can cause discomfort and restrict flexibility.
  • 💻 Utilize online fitting tools provided by bike manufacturers to determine the appropriate frame size based on your measurements.
  • 🔄 When considering a new bike, compare its geometry to your current bike to ensure a similar fit.
  • 📏 Avoid cutting the steerer tube of the bike until you're confident about the fit, allowing for adjustments if necessary.
  • 😊 It is rare for riders to actually have the 'wrong size' bike; most fit issues can be resolved with proper adjustments.

Q & A

  • What are the common signs that a cyclist might have the wrong size bike?

    -Common signs include using a very short or very long stem, with less than 90 mm considered short. Inverted stems can also indicate sizing issues.

  • How does saddle height affect bike fit?

    -Getting the saddle height correct is crucial because it influences comfort and positioning. An improper saddle height can cause discomfort and make the bike feel larger than it is.

  • What adjustments can be made if the bike feels too big?

    -Cyclists can adjust saddle height and position, as well as handlebar width and stem length, to optimize fit and comfort.

  • How can handlebar width impact the feeling of reach on a bike?

    -If handlebars are wider than a rider's shoulders, it can make the reach feel much farther away, affecting comfort and control.

  • What is the significance of crank length in bike fitting?

    -Crank length can significantly affect performance and comfort. Shortening the crank length can help fit a bike better for individuals with shorter legs.

  • What should a rider do before purchasing a new bike online?

    -Riders should use online fitting tools, compare geometry with their existing bike, and consider their riding style to determine the appropriate size.

  • What is the recommended approach for setting up a new bike for comfort?

    -Start by ensuring the saddle height is correct, then adjust the saddle position fore and aft, and finally focus on handlebar height and width.

  • How can riders know if their bike's stack height is appropriate?

    -Riders should assess their flexibility and strength in holding the bike position. If they struggle to maintain a comfortable posture, the stack height may be too low.

  • What should cyclists look for if they experience discomfort when riding?

    -They should check if the saddle is positioned correctly and if the handlebar width is suitable, as these factors can lead to discomfort.

  • Is it common for cyclists to purchase the wrong size bike?

    -It's not as common as many believe. Most issues arise from improper adjustments rather than an incorrect bike size.
