I just purchased a new Specialized Tarmac three weeks ago. When I'm descending at high speeds, the entire bike wobbles very very bad. Twice this has happened to me.....I thought for sure I was a dead man! I took it back to the bike shop the first time it happened and they tightened the head set. So now today it happens again. I must add the on the down hill I'm going about 45-50 mph with some cross winds. Can anyone shed some light on this problem????
thanks
