THE LUCKY JACK ULTRA is the rim of the weight-weenies!
This is the ultimate weapon to lighten your mountain bike. Light and resistant, it will be able to cope with most situations.
It has an unbeatable lateral stiffness / weight ratio and an unmatched level of responsiveness. It is aimed at athletes looking for lightness. Its profile is asymmetrical (offset of 2 mm), which increases the lateral rigidity of the wheel without gaining weight. The interior width between walls is 24.5, 28 or 30mm. The walls are hookless (hookless design): the strength of the rim is greater compared to that of a carbon rim with hooks. This technology has been used successfully on our rims since 2011! With SLS4 technology, the robustness is further improved and the weight saving is close to 10%. Anti-burp system: the tire bead is kept in position whatever its pressure, no risk of air loss in the corners. Technologies: Anti-burp; Asymmetric; Hookless; SLS4; Oriented spoke holes; TLR; Lucky; Jack; Duke French brand.
