I'm building up a new bike with a threadless headset. I was clueless about my spacer stack height so I temporarily set my stem height without spacers by matching existing bike setup (1.75in of drop between the saddle and top of the bar). I am surprised to see 4.5in of fork tube sticking out of my headtube. Coming from steel bike/quill stem, I imagine all sorts of terrible scenarios.
Is this safe? I presume so. Is it more structurally sound than my threaded fork/quill stem setup?
This is a cross post. Sorry.
