Why is a threaded headset better than threadless or vice versa?
I searched through the archive. I can't believe this is the first time this has been discussed but here goes. I've got my popcorn and a soda..... What do you think?!?
Some brakes are broken...
I like to use a threadless stem on a threaded/threadless quill adapter in a conventional threaded headset.
Using this combination gives me the ability to still move the quill part up and down in the steer tube for adjustabilty as well as swap out the threadless stem to change the angle from the stem as well as move the bars further forward or back. Threadless stems can be found in all different angles and lengths and often are fairly cheap.
The only large disadvantage of this system is that a quill adapter + threadless stem weighs a bit more than a dedicated quill stem -especially really LONG quill adapters. The biggest issue is the long stem bolt which needs to be strong and is always made out of heavy steel -adding much weight. And the extra material around the clamp on the quill side of the stem, along with the pinch bolts, can't compete with the one-piece lightness of a regular "7" quill stem.
Also, there are many modern quill stems that have a 2 or 4-bolt handlebar clamp with a "pop top" that allows the handlebar to be easily removed without needing to remove the bar tap/grips or breaking the brake levers down...
