An epicyclic gear system has a sun gear, a ring gear, and planet gears between the sun and ring gears. In addition, it has a carrier including a carrier flange offset axially from the planet gears and carrier pins that project from the flange into the planet gears, each with a shank anchored to the flange, a head remote from the flange, and a groove between the shank and head. Between the planet gears and the carrier pins are bearings, each including an inner race and rollers between the inner race and planet gear. Whereas the carrier pins are cantilevered from the carrier flange, the inner races are cantilevered from the heads of the carrier pins. The grooves in the pins enhance pin deflection, so that the axes about which the planet gears rotate remain parallel to the central axis of the system.
