TOPHAT DUAL-STAGE AIR SPRING

Combine the sensitivity of a coil spring with the tunability of air. Increase comfort and traction without compromising support and control, or tune your fork for hard charging without adding harshness. TopHat's dual-stage air spring system allows for lower initial operating pressure for a supple feel off the top,  while the secondary spring provides tunable support and bottom out resistance.

  • Installation and initial setup in under 5 minutes.
  • Two-stage, dual air spring system for independent tuning of beginning, middle, and end stroke.
  • 10-15 psi lower base pressure increases sensitivity off the top without a loss in support.
  • Easy to use tuning guides for riders of all experience levels from beginner to professional.
  • Adjustable floating piston height and chamber volumes for a custom tunable spring curve.
  • Unique volume spacer design adds bottom out resistance with zero effect on initial spring rate.
  • Fully adjustable without disassembly.
  • User friendly modular design is rebuildable and upgradable without special tools.
  • Includes replacement seals and chamferless socket.
  • Weighs only 30 grams more than stock cap assembly.
  • Lifetime warranty.

HOW DOES TOPHAT WORK?

CUSTOM TUNING MADE EASY

You don't need to be a suspension expert to enjoy the benefits of TopHat. Our unique tuning guide lets you choose the precise level of adjustability you want or need. Whether you prefer to quickly set-and-forget with just the basics, or enjoy structured testing and tuning to fully customize the performance of your suspension, the TopHat Tuning Guide has you covered.

  • Quickstart Guide

    Just enter your current fork pressure into the calculator and get suggested settings instantly.

    Perfect for riders who prefer an uncomplicated approach and just want to go ride. The Quickstart Guide will get you rolling from unboxing to a great feeling setup in as little as 5 minutes.

  • Standard Tuning Guide

    Looking to fine tune your fork for different terrain, racing, or switching between trail riding and big days at the bike park? The Standard Tuning Guide's easy to follow procedures give you the confidence to make effective adjustments without falling down the rabbit hole.

  • Advanced Tuning Guide

    For knowledgable suspension tuners and riders looking to get the maximum performance out of their fork, the Advanced Tuning Guide covers all the adjustment combinations TopHat offerers. From piston height adjustment and second stage volume spacers, to detailed infographics and bracketing documents, you'll find it all here.

Better than a 'coil like feel'

Air or coil? TopHat combines the advantages of both.

Designed for initial pressures 10-15 psi lower than the stock air spring at equal sag, TopHat delivers superior small bump compliance and traction. Where a traditional fork this responsive off-the-top would wallow in the mid-stroke, the secondary air chamber builds gradual support to maintain a stable ride height before ramping up smoothy to prevent bottoming. With exceptional ride characteristics and unmatched adjustability, TopHat isn't more coil like. It's better.

HAVE IT BOTH WAYS

The TopHat Advantage.

Coil springs are supple off the top but lack support on large impacts, while tuning for more bottom out control means compromising comfort and grip. Air springs can offer great support and progression but are overly harsh at the beginning, tuning for more comfort comes at the expense of support. TopHat's dual-chamber spring allows you have the best of both systems. Soft off the top, support where you need it, and plenty of tunable bottom out control at the end.

Stability and control

Perfect balance front and rear.

The key to a great handling bike is balanced suspension. While frame designers employ a range of kinematics to control the spring curve of the shock and ride characteristics at the rear wheel, it can a be a challenge tuning the fork to match. TopHat's design gives you total control to tune your fork's spring curve exactly how you want for any bike you ride.

Level up your e-bike experience

Climbing or descending, get the most out of your e-bike on any terrain.

E-bikes are faster and more powerful than ever, creating unique suspension demands on lower grade terrain and technical climbs. TopHat's increased small bump sensitivity reduces high frequency vibrations and vastly improves both comfort and grip in situations where there is less rider weight on the front end. Enjoy more traction, better control, and less fatigue over your entire ride without compromising performance on the descents.

Upgrade without worry

One size for all travel options.

TopHat isn't cheap, so we made sure you'll never have to buy a new one just because you changed your fork travel. Because it's not designed around a rigid pressure ratio or a single theoretical spring curve, TopHat isn't limited a only one travel setting. The available adjustment range combined with multiple internal tuning options assures maximum performance regardless of your travel preference. Everything you need is included, with no hidden costs or additional parts required. Ever.

Installs in minutes

No special tools or disassembly required.

Simply unthread your old fork cap and install TopHat in its place. Inflate to the suggested staring pressure using the Quick Start guide and you'll be riding in as little as 5 minutes. Fine tuning can be done in seconds and basic service completed in the time it takes to swap a traditional volume spacer.

Though not required, a custom top cap socket is included for your convenience.

Attention to the details

User friendly service and adjustment.

Designed by riders and suspension tuners for a consumer focused and user friendly experience both on the trail and in the workshop. TopHat is easily serviced and fully rebuildable in minutes without a vice, shaft clamps, or special tools. Redundant interfaces on critical components means an accidentally stripped bolt doesn't result in costly replacement or missed ride days. And with no external parts to break you'll never have to worry about TopHap being damaged in a crash.

Future proof compatibility

Modular by design.

TopHat's unique modular design isn't just about performance and ease of adjustability, it's upgradable and replaceable. As future fork models evolve, simply keep the core TopHat components you already have and replace only what you need to stay up-to-date.
