2023 RockShox BoXXer Ultimate Fork

2023 ROCKSHOX BOXXER ULTIMATE FORK

CONFIDENCE AND CONTROL. NO COMPROMISES.
Built on its high-performance legacy, the latest BoXXer was redesigned top to bottom to win races—or simply chase your buddies down the mountain. We could have made the stiffest fork possible, but we didn’t. We set out to deliver the best possible balance between stiffness, compliance, and comfort for maximum control. Two years of extensive development focusing on the critical blend of bending and torsional stiffness ratios resulted in the all-new 38mm BoXXer chassis.

After countless bike park laps, race runs, and lab test cycles, we found the perfect balance between ride quality, steering precision, and stiffness. It isn’t all about the numbers. It’s about giving you the control and feel you need to choose any line you like.

BoXXer’s 38mm stanchions are just the beginning. These upper tubes harmonize with the lowers to deliver ideal ride characteristics. Through extensive riding and testing, we tuned the stanchion wall thickness and lower leg architecture for stiffness that accepts steering input without beating up your hands. This way, you’re the one steering the fork, not the other way around.
