FLOATING AXLE

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

The all-new 36 and 38 feature a new, patent-pending, quick-release lever-operated thru-axle system, combining the benefits of a floating axle with the ease of quick tool-less disassembly. With this system, the spacing is locked via a floating sleeve, allowing repeated removal and reinstallation of the front wheel while maintaining perfect fork alignment. Floating sleeve positioning is preset at the factory, so if you don't know how to use thru-axle or just don't want to worry about it, you can just install the front wheel and get on your ride.

Available as an option is the new Kabolt-X, a lightweight bolt-on floating axle exclusively for the all-new 36 and 38 that not only reduces grams, but also increases torsional stiffness thanks to its single-sided, sleeveless pinch bolt design. Chassis alignment has to be reset every time the front wheel is removed and reinstalled on Kabolt-X and 40 floating axles, but the end result is the same: perfect alignment and perfect performance.

LOWER LEG BYPASS CHANNELS

When a fork compresses, the volume of air in the lower legs decreases, which increases air pressure. The more the fork compresses, the more the pressure increases. This effect can have the unintended consequence of preventing full displacement from being achieved. Our Lower Leg Channels help alleviate this problem by dramatically increasing the volume of air in the lower legs and thus reducing the amount of unintended additional pressure increases.

Another benefit of these channels is that oil from the lower legs flows through the upper, continuously lubricating the rings and foam rings as the fork compresses and extends throughout its stroke.

BLEEDERS

Our traps provide atmospheric pressure equalization at the push of a button. Pressure buildup in the lower legs dramatically decreases fork performance, preventing full travel and decreasing small bump sensitivity and responsiveness.

LOWER LEG ARCH

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. Our 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.

Modern frame designs and geometry trends require modern suspension design solutions. The arch design of the all-new 36, 38, and 40 is designed to pair perfectly with modern Enduro and Downhill bikes. Head tube profiles have grown larger and larger, and fork offsets shorter and shorter. Our new arch shape takes this need into account by jutting forward to provide ample headtube clearance at full compression. State-of-the-art computer modeling techniques helped us to create an organic lower leg shape that optimizes stiffness with the absolute minimal amount of material.

ELLIPTICAL STEERER

The 38's elliptical head tube is one of the many ways we've further optimized stiffness to weight, placing more material only where it's needed and eliminating every ounce where it isn't. not.

FLOAT EVOL

EVOL technology increases the volume of the negative air spring, optimizing small bump sensitivity. EVOL's linear spring curve provides softness off the top, extra mid-stroke support, and more tunable progression down.

The benefits of EVOL are further enhanced by our new lower leg channels and bleeders, which both work to reduce air pressure captured in the lower legs, allowing the EVOL air spring to operate freely without unintended interference.
