Ripping down the steepest, chunkiest, fall-line trails is a zen-like experience, simultaneously losing all sense of self and becoming one with your bike. This flow state requires the right tool for the job, a bike that knows no limits, instilling a daredevil’s confidence and monk’s focus. Chasing this feeling is what inspired us to develop the Gnarvana.

Gnarvana pairs 160 mm of Freedom Linkage-controlled travel with 29” wheels to create a bike fast enough to outrun your professional distractions and release yourself from terrestrial bonds. Come as you are and ascend to the next level with Gnarvana.

About Seatstay Kits

Seatstay Tuning Kits are available as a part of GG's Modular Frame Platform. These Seatstay Kits allow you to convert your bike from one model to another*, "tuning" your bike for different terrain, without having to buy a whole new bike.

You can use this kit to convert your current bike* to the Gnarvana. Use the Customize Build button on this page to find the necessary parts needed to complete your Modular Frame swap, plus additional customization components that you may want or need.

*Assuming you already have a 2019+ GG bike with the Modular Frame Platform.

Note: This Seatstay Kit is only compatible with alloy rear triangle bikes. Incompatible with the Revved carbon rear triangle.

What's Included?

The Tuning Kit includes all hardware necessary to install on your GG Modular Frame, including:

  • Seatstays
  • Bearings
  • Derailleur hanger and bolt

What's Not Included?

Generally, what's not included are the parts you need to remove anyways in order to swap components (e.g. axle and frame hardware) or that aren't removed in the first place (e.g. rocker). Also, any necessary components will need to be purchased with the kit (e.g. shock, fork).

If switching between wheel sizes, we recommend getting an additional lower cup for your GeoAdjust Headset. The Short Lower Cup is designed to be used with 29" front-ends; the Tall Lower Cup is designed to be used with 27.5" and 27.5 Plus front-ends.

Other things to consider:

  • Do you have the correct shock size?
  • Do you have a 29" fork? The Gnarvana is designed to work with 29" forks with 170 mm travel.
  • Do you need a 29" wheelset?
  • Do you need 29" tires?
  • Make wheel swapping quick and easy by ordering tires, rotors, and cassettes.

We'll go ahead and install any of the components on your order so you can hit the trail sooner. This includes tubeless tire setup, cassette, and rotor installation.

Revved Carbon Technology

Revved Carbon Technology is the bike industry’s newest and most advanced carbon fiber innovation. Covertly in development and testing for the last 3 years, Revved combines a revolutionary manufacturing process and evolved carbon fiber material to create the next generation of mountain bikes.

Compared to the leading types of traditional carbon fiber material, Revved’s material is over 300% more impact resistant, yet matches the strength and stiffness of the traditional material by sharing its continuous-fiber composition.

As mountain bikers, we live to explore trails in natural beauty, which is why it was important for us to also develop an environmentally-responsible material and manufacturing process. Revved sets a new benchmark in sustainable frame materials.
