I'm looking at internal (or sometime referred to as semi-integrated i believe) headsets. Am I right in thinking they can be used on standard bikes headtubes, and just replace my standard threadless headset no worries? I can't really find a clear answer

Okay thanks. Do you have any reccommendations for normal threadless headsets with a low stack height. Lower stack height the better really, that's why I was looking at internals

good call a few mm less than average.

Okay so i've got a set of forks that are only just off fitting, literally millimeters. So i'm thinking reducing the size of the headset cups will be a good way to squeeze those few mm's out and get a proper fit. How come a semi integrated one wont fit? It looks as if it just pushes into the headtube the same as a standard threadless

The head tubes flare out top and bottom for integrated headsets to accommodate the cups which are larger (still 1 1/8th steerer)

If you rested one on top of a normal 1 1/8th headtube it would be mm's out.

Can't be used on your frame. My marin has one, 5th pic down, look at the stack height and the headtube:

have a think.

could you press your current bearings that are bigger than your head tube into it?

the bearings are the same size in the internal. Wont fit/wrong design etc..
