The ZT Hugo 52 from NoTubes is one of the most innovative new developments in the area of ??the new Plus Bikes, with the special rim design (BST) achieving better tubeless properties. Due to the flat rim profile, the tire can also be supported on the inner side of the rim in order to prevent the rim from jumping off. Since the inner profile and the rim harmonics lie on the same level in this rim, the stress peaks should be more effectively distributed during the penetration. With an internal width of 49.9 mm, it is significantly wider than ordinary rims, which gives the tire a proper support width. Thus low air pressures can also be driven and the grip level can be increased. As is customary for NoTubes, the disc rim can be retrofitted on request with a 27 mm rim tape on the tubeless insert with sealing milk.
Bead Socket Technology (BST)
The BST is a patented design feature in which the design of the rim flange is oriented to the shape of the tire bead. This ensures an ideal fit of the tire on the rim for the greatest possible tubeless sealing. Likewise, the rim can be run with a classic tube .
