What methods do you use to test and confirm the optimal handlebar position after shortening crank arms, taking into account the altered riding dynamics and potential changes in body positioning? Are there specific tools, such as laser levels or plumb lines, that can help ensure accurate positioning, or do you rely on more subjective measures like comfort and feel?
Do you find that shorter crank arms require a more upright handlebar position, or is it more a matter of individual preference? Are there any innovative techniques or technologies that can be employed to optimize handlebar positioning in this scenario, such as 3D printing custom handlebar spacers or using advanced bike fitting software?
How do you balance the need for optimal handlebar positioning with the potential for altered body positioning caused by the shorter crank arms, and what methods do you use to fine-tune the fit to achieve maximum comfort and efficiency?
