Dissent Carbon Downhill Bike

Product Information

The Dissent Carbon is a high-performance mountain bike that
features a Rockshox Super Deluxe DH Air shock as standard. It is
equipped with a 4-digit Tune code or a QR code on the forks and
shocks, which provides access to specific tuning and service guides
on the FOX website. The bike is supplied with Rockshox Suspension
and comes with mid-point base settings for Rebound and
Compression.

The Dissent Carbon offers three main pivot positions, allowing
adjustment in suspension progression between 21%, 25%, and 28%. The
Main Eccentric Pivot (14) allows changes between 21% and 28%, while
the fixed Middle Main Pivot (40) provides 25% progression.

All three Dissent Carbon curves have a high beginning rate for a
supple beginning stroke, a steep mid-stroke for stability and
support, and a regressive mid-to-end stroke to prevent end stroke
spiking and limited travel usage. The bike is designed to work well
with air shocks and allows riders to go up a spring rate without
adding harshness.

Product Usage Instructions

Before setting up your suspension, read the full manual for
your shock and fork from the manufacturer’s website.
Set your sag when the bike is on a level surface. Ensure you
have something to steady yourself with or a person to hold the
handlebars while you sit on the bike.
Always set your sag before adjusting rebound and
compression.
If using a standard eyelet shock without a bearing end, make
sure to use the correct hardware size that matches the shock and
the required size for the frame. If possible, source a bearing end
shock for smooth suspension action.
For Dissent Carbon with three main pivot positions:
- Setting 1: Provides 21% progression.
- Setting 2: Provides 25% progression (default setting).
- Setting 3: Provides 28% progression.

Refer to the manufacturer’s online set-up and service guides for
detailed instructions on tuning and servicing your FOX or Rockshox
suspension components.

Note: The provided Front and Rear hardware sizes for the Dissent
Carbon are 25 x 8mm and 30 x 8mm, respectively.

Nukeproof Dissent Carbon Suspension and Main Pivot Progression Set-Up Guide
To get the most out of your Dissent Carbon you will need to set up and maintain your suspension. Suspension maintenance is specialist work, we recommend you use official service centres and service intervals are detailed in the manufacturer’s user guides. Before your first ride, the suspension will need to be adjusted. The recommended sag for the Dissent Carbon is 25%, seated with your riding kit on. You will need a shock pump to set your sag. The progression, rebound and compression settings are subjective to terrain, riding style and rider preference. Adjust the settings as you ride to find what works best for you. Any doubts about tuning your shock or using the Main Pivot Progression adjustment please consult with an authorised Nukeproof Dealer.
Before setting up your suspension, please read the full manual for your shock and fork. FOX provides a 4-digit Tune code or a QR code on their forks and shocks. This will bring up all specific tuning and service guides on the FOX website. SRAM includes set-up guides for forks and shocks in one document. Rockshox service documents are model specific and linked below. Production Dissent Carbon frames and Bikes will be supplied with a Rockshox Suspension.

Always set your sag when the bike is on a level surface and ensure you have something to steady yourself with or a person to hold the
handlebars while you sit on the bike.

Always set your sag before rebound and compression is adjusted.

Base Settings
The Dissent Carbon will be supplied with a Rockshox Super Deluxe DH Air shock as standard; initial base settings are mid-point for Rebound and Compression. Only make incremental changes to ensure suspension characteristics are familiar.

Shock Size / Tune / Upgrading If you wish to change your shock for an upgrade or a different model to your preference, please consult with your suspension supplier to ensure the shock is the correct size and the tune suits the kinematics of the Dissent Carbon. The following details will help with fitting a new shock and ensuring the tune is suitable.

Shock Size 250 x 75mm Bearing End

Note a standard eyelet shock without a bearing end can be used with the correct hardware size. Please ensure the hardware matches the shock and the required size for the frame. If a bearing end shock can be sourced, this would be
preferential to ensure the smoothest suspension action.

Tune & Progression Settings The following details will help you understand the Dissent Carbon suspension kinematics, the charts provided below will need to be referenced to help with set-up and if you change your shock need referenced by your suspension provider. The Dissent Carbon has a progressive layout, this ensures more support the further you push through the travel ensuring a stable and predictable ride. The new suspension kinematics builds on the V1 Dissent Alloy and has been improved for the Dissent Carbon. A high beginning rate gives a more supple beginning stroke, with a steep mid-stroke to give good stability and support and a regressive mid-to-end stroke to prevent end-stroke spiking and limited travel use. The added sensitivity allows the rider to go up a spring rate without adding harshness, to work better with air shocks and overall, still pedals exceptionally well.
There are 3 possible Main Pivot positions on the Dissent Carbon. The 3 positions allow adjustment in suspension progression between 21%/25%/28%. As shown adjacent from the Dissent Carbon exploded diagram, the Main Eccentric Pivot (14) allows changes between 21%/28%, fixed Middle Main Pivot (40) is 25%.

Leverage Ratio
All 3 Dissent carbon curves have a high beginning rate to give a more supple beginning stroke, a steep mid-stroke to give good stability and support, and a regressive mid-to-end stroke to prevent end stroke spiking and limited travel usage. You can also see the difference between the new and old curves in the beginning stroke. This was done to add sensitivity, allowing the rider to go up a spring rate without adding harshness and work better with air shocks.

Anti-Squat
Flipping the progression lever also affects the anti-squat %. This works well as the progress setting has more antisquat to help control the very soft beginning stroke. Whereas the linear setting has a lower anti-squat, but this setting also has more support in the beginning stroke, so requires less anti-squat.

How to adjust your Progression Settings Now you understand the Dissent Carbon rear suspension Kinematics in the 3 available settings, the following details how to switch between these settings to get the suspension dialled to your preference and terrain.
Progression Setting 1 (21%) and 3 (28%) The Dissent Carbon will be supplied with the Main Eccentric Pivot Axle (14) installed to the frame. With the following process, the Main Eccentric Pivot Axle (14) can be flicked up and down to switch between the two progression settings.
– Loosen the Main Pivot Axle (13) anti-clockwise a complete revolution with an 8mm Allen Key. This will free the Main Pivot Flip Axle (14) to move up and down.
– Select your progression preference by moving the Main Pivot Flip Axle (14) fully up and down.
– In the down position progression setting, 1 is 21% and in the up-position progression setting, 3 is 28%.
– Once you have selected your progression preference retighten the Main Pivot Axle (13) to 25Nm with an 8mm Allen Key Torque Wrench.
