Upper headset gap
« on: June 04, 2026, 11:07:51 AM »
Hi,

I have a question about the upper headset gap.

Mine is almost close to nothing, I can't even put a sheet of paper from the front of it. But it turns well on the right and left.

Is it better to have a small gap or could it stay line this (see the photo)?

I have a LCR 018 frame

Thank you for your help !

What kind of c-ring did you use? One like this? https://it.aliexpress.com/item/1005010178624422.html

If, as you say, the handlebar rotates freely and does not bind, you should be fine; over time, you may lose some paint from the top of the headtube but you wouldn't see that anyways.

For what it's worth, Deda in some of their technical drawings show a headset gap of 0.8mm; if you wanted to, you could add a 0.25 or 0.5mm headset shim/microspacer.

Thank you for your answers. I didn't put any small internal spacer but there is one of 0,7mm included with the frame. I wanted to try without it as some others did but I will add mine to the headset.

make sure your headset does not bind under heavy breaking.

Ok I've added a 0,7mm spacer and checked the potential bending of the headset and now everything's good. Thanks for your help guys !
