A bicycle stem includes a handlebar clamping portion and handlebar clamping member having respective first and second clamp surfaces defining interlocking joints. Each interlocking joint may include a recess and a projection therein to resist relative sliding motion in a direction generally parallel to an axis of a handlebar-receiving passageway to thereby resist torsional loading. A plurality of fasteners may secure the handlebar clamp member to the handlebar clamping portion.
