Part 2 of our series on saddle height in bike fitting continues with our episode this week The Science of Saddle Height. Our guest Dr. Rodrigo Bini joins us remotely from Latrobe University in Australia.  

While last week, our guest Tom Wiseman focused on pelvic stability as the indicator of potential saddle height problems, Dr. Bini delves into the research that supports saddle height change.  We talk about some of the following great topics:

  • The amount of saddle height change needed to show statistically significant values in force or oxygen uptake
  • Knee angles
  • Static fitting knee angle vs. dynamic fitting knee angle
  • Should I throw out my Goniometer? Spoiler Alert – No
  • Technology in Fitting
  • Much much more… 

If you missed last week’s episode, you can listen to it here.

Rodrigo Bini, PhD, is a Lecturer and researcher in Exercise and Sports Biomechanics at La Trobe University – Bendigo Campus in Australia.

Currently, Rodrigo is an associate Editor of the Journal of Science and Cycling and the Human Movement journal. He also is a member of the Editorial Board of the Sports Biomechanics Journal, the Journal of Sports Sciences and the European Journal of Sport Science.

Rodrigo is also one of the editors and authors of many chapters in the book Biomechanics of Cycling, published in 2014. Rodrigo has published over 60 articles, the majority involving studies on sports biomechanics and he pursues particular research interests in the application of muscle mechanics principles in sports actions, with special attention to cycling and running.

    I switched off after he said 2cm change in saddle height won’t make any difference in force or power output. Mmm..

      Hi Adam,
      Dr. Bini is looking at this from the research perspective. For many, fit is much more subjective and even in research, they analyze the bell curve but not necessarily the outliers. What is true for some may not be true for all but the perspective is valuable. We know that many cyclists adapt to positions on the bike and some are more malleable than others. I appreciate you listening.

    I was anticipating this so much for a number of reasons not the least of which was the possibility that he might address not just competitors but adjustments for the aging or old riders. Sadly, I could barely understand what he was saying due to his heavy accent and having to figure out that “he” means “here” and many other examples of speech and language in Australia.
    Perhaps it is just me.
    Thank you for offering this program though.

      Hi Ren,
      Dr. Bini does have a strong accent coming from Brazil and studying in Australia. Our conversation could have likely been a 3-hour podcast and we only touched the surface of saddle height and its effects when it comes to looking at efficiency (oxygen uptake) and force.

      You’ve inspired me though for a future podcast as adjustments for aging riders is a great topic. I think that focusing on that as a whole will give you much for information than looking at saddle height alone which is only a small piece of the puzzle.
