Do short cranks increase leg speed, or are they just a marketing gimmick for riders who cant actually ride fast? Ive been seeing a lot of discussion about the benefits of short cranks, but most of it seems to be anecdotal and based on unproven assumptions.
Id love to see some actual data or scientific studies on the topic. For example, whats the optimal crank length for a rider of a given height and inseam? Does it vary depending on the type of riding youre doing - e.g. climbing, sprinting, or endurance?
Im also curious to know how short cranks affect the biomechanics of pedaling. Do they actually allow for a more efficient or powerful pedal stroke, or do they just feel faster because youre spinning more revolutions?
And what about the relationship between crank length and cadence? Do short cranks actually encourage a higher cadence, or is that just a result of the rider trying to compensate for the shorter crank length?
It seems to me that a lot of the arguments in favor of short cranks are based on the idea that theyre more efficient or easier on the legs, but Im not convinced. Ive seen plenty of riders who swear by their 165mm cranks, but when you put them on a set of 175s, they cant tell the difference.
So, lets get to the bottom of this. Can someone please provide some actual evidence or data on the benefits of short cranks, or are they just a fad thats going to fade away in a few years?
