How it rides

From Argon 18’s own numbers for the M(54-56), not marketing copy.

aggressive · neutral handling

Down to the S(51-53): the bars sit much lower — a more aggressive front end. Also: overall posture feels noticeably racier / lower up front.
Up to the L(57-59): you'll sit a bit more stretched out to the bars. Also: the bars sit noticeably taller — a more upright feel.

From your saved height and inseam, not a height range.
