Size S, for heights from 1.55m to 1.68m. Impeccable frame, as seen in the photos, with small signs of normal use. SRAM GX EAGLE 12 groupset, XT brakes, SWITCH dropper post, Damil carbon handlebar. The MTB has been used very little because I mainly use road bikes. Mechanics are perfect, no maintenance needed. I will include a new rear tire and a new chain as a gift.
