i did cut the stem. and also cut a slit 40mm along it where it should widen when you tighten the plug. but what i didn't realise was that now i'll need a new stem bolt with threading that goes further up. also realised that the stem tubing gets thicker the closer it gets to where it bends, so it'll be harder for it to open up when tight.
meanwhile i came across a stem with a much smaller height which goes in enough but is too long.
i think the issue is that its a custom built frame and the steerer is designed for quite low stems so the tubbing thickens from when its 50mm away from the fork.
anyway, i'm now hoping to get a stem with a very low maximum height (less than 40mm) and only around 60mm length.
