I am trying to find valve stems to fit my 4.5" Fuch and can't find an up to date answer anywhere.

The standard snap in TR415s won't fit properly / won't reliably stay in. I'm aware there was an older source for these a few years ago which worked better but can't find any now.

I found some screw-in metal valve stems in the wider 15mm / TR415 size but they aren't long enough for the thickness of the hole in the rim, and also the nut won't hold it properly at the 45 degree angle it needs to seal the valve to the rear face of the rim.


1. does anyone have a source for (ideally good looking) valve stems which are both wide enough and long enough?

2. how have people dealt with the 45 degree angle of the stem protruding to the front face? - it's not a problem with snap in valves but with the screw in type having such an angle stops you screwing the retaining nut down properly.

3. is there a completely different option I haven't thought about? (I can't run tubes in my tyre size by the way).


Any help much appreciated I've been scratching my head for weeks over this one.
