OK, so this is my first attempt at tubeless and maybe I have just chosen the Devil’s combo?
I have some new 2021 Mavic Crossmax hookless rims and a Racing Ralph EVO tyre. Using Stan’s tubeless valves.
Having watched many vids I thought I’d see if the tyre will seat without tubeless liquid inside.
No chance, the bead on each side just sits in the trough in the middle of the rim.
I have tried to pull the bead across so it sits next to the rim but it is hard work and the bead will slip back on the tubeless tape.
There is a clearly no way that an even vaguely airtight seal is being created and so I am having a pause to consider the next approach. The most obvious next step seems to be to add Stan’s tubeless solution but I suspect I am simply going to have the same issue of the bead not being near the rim, but complicated by everything being covered in white gloop.
Apologies for the sounding off but does anyone have first-hand experience of how to make a Mavic UST hookless rim form a seal with a tyre (its basic job!).
Thanks in advance for any help.
