UST Tubeless rims (channel without holes)
Since 2021 RaceFactory is the only European manufacturer to switch to 100% UST (Universal Standard for Tubeless) rims without holes in the rim, both for the MTB and BDC sectors. The reasons are very clear: they are superior in everything to the classic drilled "Tubeless Ready".
In traditional "Tubeless Ready" drilled rims, to make the rim truly tubeless, the special tape must be applied in the rim channel to seal the holes.
In "UST" rims (tubeless without holes) there are no holes in the rim channel. The only hole present is the one for the inflation valve. The assembly of this version is much more time-consuming and laborious, because the nipples must be inserted into the rim one at a time and brought into position for assembly.
The tacking of the wheel is slower, the pre-tensioning of the spokes can only be done externally, with the spoke wrenches, and screwdrivers cannot be used . That's why there is an assembly surcharge.
The difficulties stop there, and they are only for the assembly.
Our SWBT and AeroPluse™ series with UST channel have several advantages over the classic drilled "Tubeless Ready".
RaceFactory it is also the only wheel manufacturer in Europe to assemble UST closed rims with UHDPE Berd spokes, offering the maximum of the two technologies and maximum lightness.
