My Ironman is a little too short for me. It currently has what I believe is a 90 mm quil threaded stem. I would like to use a 110 mm steam which would put the reach closer to my other bike. I also am not a fan of the classic drop bars and would prefer a modern compact bar.

I have seen 110mm quil stems but no compact bars that are compatible. I have compacts that I like with 31.8 diameter so then I need a threadlesss stem. I have seen the threaded to threadless adapters. Are those decent options or I am better off going the more expensive route of new headset and new fork (would probably upgrade to carbon fork if I did this)?
