Can it be argued that the conventional methods of assessing bike fit, such as using a plumb line or measuring the riders knee angle, are outdated and should be replaced with more modern and technology-driven approaches, such as 3D scanning or advanced motion capture systems, which can provide a more accurate and detailed analysis of a riders position and movement on the bike? Are these new methods worth the often-significant increased cost, or are they simply a luxury for professional riders with deep pockets? And what about the potential drawbacks of relying on technology to assess bike fit, such as the risk of over-reliance on data and the loss of traditional bike-fitting skills?
