Length option 2	41.25 in	104.8 cm

The source data lists multiple length choices without assigning each one to a specific club/head label, so the page keeps them as numbered options rather than inventing a mapping.

What the numbers mean

Playing length is a build specification, not a universal fitting target.

Player height, wrist-to-floor measurement, posture, strike pattern and swing-weight goals can justify a different finished length. Changing shaft length can also change lie interaction and feel.
