I just got a 2009 cannondale6-5 with SHIMANO 105 and ultegra rear derailleur.It was smooth as can be and climbs hills like no body's business.Light and fast using cannondales use of carbon fiber rear triangle and front forks.Have put on a 1000miles on this bike no crashes and bike stored inside.Iam hearing some noise in the steering and when i hit the front brakes and move the bike forward and backwards with the front brake engaged i hear some creaking noise like play in the steering.I tightened down the top Bolt but the play is still there.Any one have an answer.
