Trek Madone Size Chart
Madone uses Trek's road alpha letters, not centimetre labels, and Trek publishes the Madone table separately from the brand-level road chart. The two disagree on S and M: Madone S is 50 cm where the brand chart says 52, and Madone M spans 52-54 cm where the brand chart says 54. Read the Madone table on this page before translating a size.

How neighboring sizes compare
If two sizes both fit, compare reach and standover rather than assuming the larger size is more comfortable.

Sizing notes
Why height alone is not enough
Riders with the same height can need different sizes because inseam, torso length, flexibility, and preferred handling differ.
3 checks
Madone is Trek's aero road platform. Trek publishes the Madone sizing table separately from the brand-level road chart, and the two disagree on M: the Madone table says 52-54 cm while the road chart pairs M with 54 cm.
Trek publishes both a rider height range and an inseam range for every Madone size. When they point at different rows, inseam and standover decide it.
Stack grows faster than reach across the Madone range: XS to XL adds 103 mm of stack but only 32 mm of reach, so stepping up a size raises the front end more than it lengthens the cockpit.

What frame size is a Trek Madone L?
Trek lists Madone L as 58 cm, covering riders from 179–188 cm with an 84–88 cm inseam. It is the largest size that still pairs with a single centimetre label; XL spans 60-62 cm.
Is Trek Madone M the same as 54 cm?

How tall is a Trek Madone ML for?
Trek publishes ML for riders from 173–179 cm (5'8"–5'10") with an 81–84 cm inseam. Trek lists ML as 56 cm, and it adds 16 mm more stack than M while reach grows only 5 mm.
