I am almost too embarrased to tell you what i found out, but i will. I had checked the tire pressure in both tires before our ride and had 54 in the rear and 34 in the front. The next day after the trip and posting my problem i rechecked the tires and found that the back was o.k. But the front had leaked through the valve stem and only had 18lbs of air in it. I put 34 lbs back in it after tightening the inner valve stem core and it handle perfect. Talk about feeling "stupid". Thanks for all your input and i won't be forgetting this again!
