26" 2.1 80mm presta valve inner tubes???

Hi everyone
Could anybody point me in the direction of some 26" 2.1ish inner tubes with 80mm presta valve length?? For Hed Ringle xc rims. I'd rather stay away from valve extenders they are pants

Re:

Are you just screwing the extenders on or are you removing the presta valve core assembly completely then screwing the core into the end of the extender? If you use them correctly then extenders work perfectly, if you just open the valve on the inner tube and screw on the extender then they won’t work properly.

You need decent inner tubes with removable cores and decent extenders with an internally threaded end. Using PTFE tape will seal the extender to the inner tube and the valve core to the extender end.

I doubt anyone makes 26 x 2.1 with an 80mm valve, it’s just a bit too niche these days

I removed the core completely then screwed the extender on with ptfe. They leaked air slowly
