I have just put my recently purchased fsa headset into the frame but seems rather loose, as I didn't need to use any force what so ever to put it in the headtube, now will this be ok once it is all tightened up with a stem fitted ect (aheadset by the way) or have I got problems which I'm assuming I have. My old headset was fine so wondering if its the headset thats the problem or if my frame as got some kind of funny hedtube size, old cannondale m500 if thats any use just wondering if they had some funny size or something. If not I guess its time to get the callipers out and measure both to find out whats wrong Doh!
