DUKE RIM LUCKY JACK SLS4
The Lucky Jack SLS4 are the flagship of the XC carbon range. They are designed for all kinds of XC.
The Lucky Jack SLS4 are the flagship of the XC carbon range. They are designed for all kinds of XC. The front/rear widths are differentiated: 30mm/28mm or 28mm/26mm depending of the tire section. These rims are used in the XCO World Cup by the BMC Racing Team, 3-time world champion in 2022 with Pauline Ferrand-Prévot and used by Matthieu Van der Poel and many other riders.
It is the ultimate weapon for demanding races. Light, rigid and strong, it will be able to cope with all situations. It is characterized by an unbeatable lateral stiffness/weight ratio and has an unequaled level of responsiveness. For athletes looking for the must. The rims feature a new, modern, lower and wider profil with an asymmetrical profile and hookless walls. The 2.8 mm offset makes it possible to further close the spoke brace angle and thus increase the lateral rigidity and stability of the wheel without taking weight. The tensions of the spokes between the two layers are more balanced, which guarantees better durability of the wheel. The front and rear widths are differentiated (6TERS concept): the greater width at the front will give a larger volume to the tire to provide more grip in the supports. The rear rim has a smaller section to improve comfort and impact resistance. The hookless walls make it possible both to reinforce the rim and to reduce its weight. This technology has been used successfully on our rims since 2011. Anti-burp system: the tire bead is kept in position whatever its pressure, no risk of air loss in the corners. DUKE owns its manufacturing tools.
