Mountain bike size 29 The bike is modified, weighing around 13 kg. It has changed wheels, handlebars, handlebar risers, and the gears front and rear, as well as the grips and gears. I've invested a lot in it and taken care of it. It doesn't need anything. One front gear, 12 rear gears, Hydraulic brakes, Oil suspension. The actual condition is not different from what is stated.
