Sorry for the dumb question, but I got my Renn Disc today and am having a heck of a time getting this tube pumped up. I tried three different pumps and none of them fit in the cut-out. What is everyone else using? Thanks!
Silca Track Adapter aka “crack pipe”.
I ran into the same thing. That little brass adapter is ~$12. In speaking to Frank @ Renn, he mentioned that some use a tube with 48mm valve and then are able to angle it out far enough to get a standard pump head onto it(I had already bought the adapter so I haven’t tried that).
One piece of advice~don’t thread the little nut over the valve. There is nothing solid for it to seat onto and it actually compresses down into the corrugated material between the access hole and the rim. I had to use a pair of needle nose pliers to get it unthreaded and backed out(that would have been a real hassle if I had left it and had a flat during a race).
For flats during a race, the small CO2 adapter will fit into the access hole and onto the valve(at least it appears that way~luckily, I haven’t had to try firsthand).
Good luck & enjoy the disk~(It’s a great value for the $$$)

PS: I can’t wait for their upcoming front wheel
Get the long stem tube and you just bend it out. Nothing to it.
