Narrative:
Departing den, first officer's leg. Aircraft was given to first officer for takeoff. Strong crosswind left to right. He was not keeping aircraft aligned with centerline, so I made small correction with tiller. He then stated that he had no rudder and called abort. I aborted 60-70 KTS. He then informed me that the rudder adjustment came out of locked detent and went full forward. After abort on taxi back, he checked rudder pedals again to assure that they stayed locked. We checked all instruments and temperatures. They were all normal. We departed with no further problems.
