Abstract: A skate with in-line rollers or wheels (1) comprises a chassis (5), a shoe (4) mounted on the chassis, a front wheel unit (6) and a rear wheel unit (9), the units (6, 9) pivoting on the chassis (5) about respective pins (13, 14) transverse to the direction of movement of the skate (1). A coupling link (15) is provided for coupling the wheel units (6, 9) together in such manner as to cause them to pivot together and in the same direction about their respective pivots pins (13, 14). This skate can flexibly cross discontinuities in the ground of small height or depth with all of the wheels (7, 10, 11) remaining in contact with the ground.
