Considering the drastic shift in crankset design and the increasing popularity of shorter crank lengths, its surprising that the impact on saddle setback hasnt been extensively explored. Most cyclists still rely on outdated guidelines and anecdotal evidence when adjusting their saddle position. Id like to challenge the conventional wisdom and explore the relationship between crank length and saddle setback.
Assuming a shorter crank length reduces the overall distance between the riders feet and the bottom bracket, would it be more beneficial to increase or decrease the saddle setback to maintain optimal pedaling dynamics and prevent excessive strain on the knees and lower back? Would a shorter crank length necessitate a more forward or rearward saddle position to compensate for the altered biomechanics?
Moreover, how would the type of riding (e.g., road, mountain, or gravel) influence the ideal saddle setback with shorter cranks? Would a more aggressive riding position, such as that of a road cyclist, require a different saddle setback compared to a more upright position, like that of a mountain biker?
Furthermore, what role would the riders individual anatomy, such as leg length and torso shape, play in determining the optimal saddle setback with shorter cranks? Would a rider with longer legs require a more forward saddle position to maintain proper pedaling form, while a rider with shorter legs might benefit from a more rearward position?
Lastly, are there any potential drawbacks or risks associated with adjusting the saddle setback to accommodate shorter cranks, such as increased pressure on the hands or wrists, or compromised bike handling? How can cyclists balance the benefits of shorter cranks with the need for optimal saddle positioning and overall comfort on the bike?
