reasonLapierre publishes no defensible conventional equivalence for its letter sizes. Lapierre publishes geometry only. The centimetre figures retailers print beside its letters are its seat-tube lengths: the Xelius DRS geometry row 'A: Seat tube length (mm)' reads XS 440, S 460, M 490, L 520, XL 550, XXL 580, which is exactly the retailers' 'S (46 cm)', 'L (52 cm)', 'XL (55 cm)', 'XXL (58 cm)'. A Lapierre L is a bike for a rider the rest of the market sells a 56-58 to, so reading its 520 mm seat tube as 'conventional 52' would send a 52 cm rider a frame two sizes too big.
