Finding the right saddle height formula for shorter cranks seems to be a widely debated topic, with various methods and calculations floating around, but whats the most effective approach when the standard formulas dont quite apply.
Most formulas for determining saddle height are based on the riders inseam and crank length, but when shorter cranks come into play, these formulas start to lose their accuracy. This raises questions about the validity of these formulas and whether they can be adapted for use with shorter cranks.
For example, the traditional method of using the LeMond formula, which involves measuring the distance from the center of the bottom bracket to the top of the saddle, seems to be less effective when cranks are shorter than 170mm. This method relies heavily on the riders inseam, which may not be the most accurate determinant of saddle height, especially when shorter cranks are involved.
Another approach is to use the method popularized by Dr. Andy Pruitt, which involves using a combination of the riders inseam and the angle of the knee at the bottom of the pedal stroke to determine saddle height. However, this method also relies on the riders inseam, which may not be the most effective starting point when shorter cranks are in use.
The use of motion capture and 3D analysis has also been suggested as a means of determining the optimal saddle height, but this approach is not feasible for the average rider, and the results may not be transferable to different riding conditions.
Considering the limitations of these methods, what alternative approaches can be used to determine the optimal saddle height for riders using shorter cranks? Are there any formulas or methods that have been developed specifically with shorter cranks in mind, or are there other factors that should be taken into account when determining saddle height?
Can the use of bike fit software, which typically involves a series of measurements and calculations, provide a more accurate determination of saddle height, even when shorter cranks are involved? Or are there other factors that need to be considered, such as the riders position on the bike, the type of riding being done, or the individuals unique anatomy?
Ultimately, whats the most effective way to determine the optimal saddle height for riders using shorter cranks, and how can we adapt existing formulas and methods to account for the unique challenges posed by these components?
