When considering the switch to shorter cranks, such as 165mm, what are the implications for saddle position, and do these changes necessitate a re-evaluation of overall bike fit. Specifically, how do the reduced crank length and altered pedal stroke dynamics influence the riders position on the saddle, and are there any notable differences in this regard compared to standard or longer crank lengths.
Furthermore, are the adjustments to saddle position primarily driven by the need to maintain optimal knee angle and pedaling efficiency, or are there other factors at play, such as changes to the riders posture or weight distribution on the bike.
Additionally, how do the effects of shorter cranks on saddle position vary across different riding styles, such as commuting, leisure, or performance-oriented riding, and are there any notable differences in this regard between riders of varying experience levels or physical characteristics.
Lastly, what role do bike manufacturers and professional bike fitters play in recommending and implementing shorter crank lengths, and are there any established guidelines or best practices for determining the optimal crank length and corresponding saddle position for a given rider.
