A lot of times (nearly all the time) they seem way too underbuilt as far as the headtube goes. So If that cracks or ovalizes you have to buy an entirely new frame. These headsets might be great for some of you Pros out there but they're really not all that logical for average riders like myself. Who have to pay for everything we ride with and let me tell you my paycheck really isn't that big. I'll stick with the standard old headtubes and headsets thank you. Because if I damage a cup in anyway its MUCH cheaper to replace!
