167.5mm cranks have been touted as a game-changer for comfort on long rides, but wheres the concrete evidence to back this up? It seems like every other thread on this forum is filled with anecdotal claims of improved comfort, reduced fatigue, and increased efficiency, but how many of these claims are actually supported by scientific data?
Are we just buying into the latest marketing hype, or is there real substance behind the idea that shorter crank lengths are better suited for endurance riding? Im not talking about the pseudo-scientific explanations that get trotted out in every thread, either - I want to see actual studies, data, and research that demonstrate a clear benefit to using 167.5mm cranks on long rides.
And dont even get me started on the whole bio-mechanical advantage argument. If were going to claim that shorter cranks reduce the stress on our joints, then wheres the data to support this? Have there been any actual studies on the effects of crank length on joint stress and fatigue?
Im not trying to be contrarian here, but it seems like were all just taking this stuff on faith. I want to see some hard evidence that 167.5mm cranks are actually worth the investment, rather than just relying on hearsay and speculation.
So, Ill ask again: wheres the proof? Can anyone point me to some actual research or data that supports the idea that 167.5mm cranks improve comfort on long rides? Or are we just drinking the Kool-Aid on this one?
