1. A bicycle fork, comprising:

  • first and second telescopingly engaged tubes configured to move closer together during compression of the fork;

    an adjustable lock-out valve, the lock-out valve having a plurality of operator-selectable positions, one of the operator-selectable positions of the lock-out valve at least substantially inhibiting the first and second tubes from moving closer together when subjected to a compressive forces less than an operator-selectable threshold pressure;

    a first external adjuster permitting selection of the positions from a location external of the fork;

    a manually adjustable blow-off valve allowing the first and second tubes to move closer together in response to a pressure imparted on the blow-off valve during compression of the fork being equal to or greater than the operator-selectable threshold pressure when the lock-out valve is in its substantially inhibiting movement position; and

    a second external adjuster, the second external adjuster permitting adjustment of the threshold pressure from a location external of the fork.
