                        Our XC icon. Reinvented.
Now 10% lighter than the previous generation, the Lucky Jack SLS5 also gains 15% more vertical compliance. Ultralight yet tough, it delivers even more dynamic ride feedback and unmatched comfort on the most demanding courses.
 Available in two internal widths and three weight options, it's trusted by top World Cup athletes such as Loana Lecomte, Kate Courtney, Jordan Sarrou, Titouan Carod and David Valero.
Recommended builds:
 245 g*: XC front
 285 g*: XC rear or [very] aggressive XC front
 350 g*: [very] aggressive XC rear
*Weight without stickers (removable). Add 8 g per rim.

Our SLS5 (Super Light Series 5) process combines optimized carbon fiber layups with an exclusive aerospace-grade resin. 
10% lighter than its SLS4 equivalent. 
15% more vertical compliance for better dynamic response. Increased resistance to lateral stresses and vertical impacts. 
Enhanced vibration damping for greater comfort and control.
ImpactGuard – Energy-Absorbing Inserts High-resilience 
inserts, pressure-injected into hollow cavities on either side of the rim, absorb both low and high-intensity impacts. They offer maximum protection without adding unnecessary weight – their density is comparable to our carbon fiber.
 SpokeCore – Molded Spoke Holes 
Thanks to an advanced manufacturing process, the spoke holes are directly molded into the rim structure. This eliminates the weaknesses and rigidity alterations often caused by drilling. The result : a one-piece construction that increases durability, allows for fewer spokes, maintains precise stiffness control, and ensures exceptional reliability.
By shaving weight off the new Lucky Jack, we’ve made the bike more agile through technical sections and more responsive to pace changes. But weight isn’t everything. Thanks to our DRC (Dynamic Response Comfort) technology, fully integrated into the SLS5 process, the new Lucky Jack delivers controlled deformation and optimized rebound management. What does that mean on the trail? 
More responsiveness 
Energy stored when entering a corner is unleashed for explosive acceleration out of it. 
Better grip 
Whether braking or accelerating, power transfer to the ground is optimized. You’ll feel more traction in corners and through technical terrain. 
Increased comfort 
Less fatigue in your upper body, even on long, demanding rides. 
Greater control 
Your bike feels calmer and more stable when the terrain gets rough. 
Proven reliability 
Unlike aluminum, carbon fiber doesn't fatigue under stress. By diffusing force across the rim, it reduces the risk of failure.
