I have just obtained a set of Crank Bros Cobalt 2's, which as you may be aware require no rim-tape for tubes as the spokes are not exposed in the rim. I'm quite happy to run tubes but would like to give tubeless a go.
So my questions relate to how I run a tubeless set-up.
Looking at Stan's No-Tubes website I see two options:
1. The Standard Rim Strip with presta valve incorporated
2. Universal 35mm Valve Stem
If I use option 2 how does the valve attach to the rim? Does it screw in? Or does the pressure hold it and seal it?
Many thanks in advance and sorry if it seems a dumb question but I can't work it out
