Floating axles might look similar to other axles, but in fact they offer a distinct performance advantage due to their unique ability to match the exact width of the fork’s wheel mounting surface precisely to the front hub flange spacing, thus creating perfect chassis alignment and eliminating unwanted friction between the upper and lower fork legs. Floating axles provide much smoother suspension movement throughout the entire range of the fork’s travel, notably improving sensitivity and overall ride quality.

As a fork compresses, the air volume within the lower legs decreases, increasing air pressure. The more the fork compresses, the more pressure increases. This effect can have the unintended consequence of preventing full travel from being achieved. Our lower leg channels help alleviate this issue by dramatically increasing air volume within the lower legs and thereby reducing the amount of additional unintended pressure ramping.

The lower leg bleeders allow for atmospheric pressure equalization at the simple press of a button. Pressure build-up in the lower legs dramatically decreases fork performance, preventing full travel from being achieved, and diminishing small bump sensitivity and responsiveness.

Stiffness-to-weight is the ultimate metric for bicycle design. Engineers invest countless hours poring over every ounce of material in an effort to optimize this critical ratio. The all-new lower leg design pulls out all the stops, shaving every possible gram while making sure not to compromise stiffness or strength requirements of modern enduro and gravity style riding.

The GRIP2 damper is the benchmark for unparalleled ride quality and ultra-precise adjustability. GRIP2 includes the patented Variable Valve Control (VVC) technology which allows for external fine-tuning of suspension performance. GRIP2 achieves with the twist of a knob what typically requires the time consuming and complicated task of completely disassembling and reassembling the fork.

EVOL technology increases negative air spring volume, optimizing small bump sensitivity. EVOL’s linear spring curve delivers plushness off the top, extra mid-stroke support, and more tunable bottom-out progression.
