Why Coil?

Air springs have improved substantially over the years - and we've been at the forefront of air spring development for years, so we've got no bridges to sell you.

Yeah, coils are heavier than air, and for some riders that alone is a dealbreaker - fair enough. The advantages of coil springs, however, are clear:

Zero stiction or friction in a coil spring. And no moving seals in the spring system to wear out, cause friction or leak.

Zero spring rate variation allowing more mid-stroke support and consistency.

More oil in the fork - lubrication and service life are improved.

In short, improvements in sensitivity, grip, compliance, mid-stroke support and consistency, with reductions in harshness and hand pain.

BOTTOM OUT RESISTANCE

Adjustable Hydraulic Bottom Out Control

Low weight aside, air springs outperform coil springs in one critical area: bottoming resistance. The hydraulic bottoming control valve addresses this with a speed sensitive shimmed valve which engages progressively and seamlessly in the last 50mm of travel, bringing the fork to a smooth and controlled stop at the end of the travel. High energy and low energy inputs are effectively managed without harshness. Easy tool-free external adjustment ensures you get as much or as little bottoming resistance as you need at the turn of a dial. Increased stability as energy is dissipated, rather than stored and thrown back at you.
