Dreadnought V2 FAQs

Dreadnought V2 FAQs

What is the Recommended Sag?

We recommend 28-30% sag. This equates to 16.8 – 18mm of shaft insertion.

What is in the box?

In a complete bike box you will find tubeless sealant and an AXS charger.

In a framekit you will get both 27.5” and 29” ‘0’ position dropouts.

Can I run a coil shock?

You can! For wider compatibility we’ve increased spring clearance in the shock tunnel as well as headroom between the shock reservoir and downtube. Please contact us directly for tuning advice (contact@forbiddenbike.com).

Do I need a lower chain guide?

Due to the longer travel and hard hitting nature of Dreadnought V2, it ships with a custom single position MRP MXg chain guide based on the ISCG-05 bolt pattern. Through testing we found this improves shift performance with minimal compromise to drivetrain feedback. Choosing to remove it will result in less than satisfactory shift performance and premature drivetrain wear, and slipping.

What chain guide does Dreadnought use?

Dreadnought uses a custom version of MRP’s MXg guide. We chose to use a custom fixed position backplate to remove any potential inconsistencies in drivetrain performance. Excluding the backplate, all spare parts are standard and available directly from MRP or your local MRP distributor/dealer. If you require a new backplate in future, the standard ISCG 05 slotted backplate mounted, and rotated to the extreme anti-clockwise will put it in the same position as the fixed guide that came with your bike.


What length chain does the Dreadnought use?

With a 32t front chainring we recommend the following number of links in the chain for each size: S1:124 / S2:126 / S3:128 / S4:130

What are modular dropouts?

Dreadnought utilizes our modular dropout system, shared with Supernought. This allows for adjustment of rear center length to fine tune rider weight balance on each axle, we call it Bias Adjust. Dreadnought frames ship with 2 sets of dropouts for both 29” and Mixed wheel (29 front, 27.5 rear) set ups.

Can I run an MX (Mixed) set up?

Yes, Dreadnought V2 is available as a complete bike in either 29/29 of MX wheel configurations.

Framekits are shipped with the dropouts for both MX and 29/29 wheel configurations.

Additional dropouts can be purchased to modify your choice.

Can I run a 29” wheel in the -10mm dropout position?

No. Running a 29” wheel in the -10mm dropout will result in inadequate tyre clearance for mud and debris.

Can I run dual 27.5?

Yes you can. However, it should be noted that your BB height will be reduced.

27.5 forks can be used too, as long as the axle to crown doesn’t exceed 593.7mm

What is the maximum rear tire width?

With a 29” chainstay: 2.5” (maximum width of 60mm at the widest part of the tread)

With a 27.5” chainstay: 2.6” (maximum width of 66mm at the widest part of the tread)

What drivetrains can I run?

Dreadnought is equipped with SRAM’s Universal Derailleur Hanger. This allows fitment for all modern drivetrains.

Why does it have an idler?

The idler is a critical component in our Trifecta suspension system.

Can I run a dual crown?

Yes, as long as the axle to crown doesn’t exceed 593.7mm.

Can I run a longer stroke shock, 62.5mm or 65mm stroke?

Running any components that are not originally intended for use on the bike will void your warranty. This includes a shock with a longer than stock stroke (stock stroke = 60mm). A longer stroke shock will result in insufficient clearance between frame members during bottom-out condition, failing to meet our minimum clearance requirement.
Cycling the suspension through its travel might make it appear that there is sufficient clearance, however, this does not account for the compression of the internal bottom-out bumper.

Why do you use size specific dropper post lengths?

Our bikes come with size specific seat post lengths that allow for different rider heights. The amount of drop is noted in our spec sheets under each model. We choose seat post lengths based on the seat posts ability to be inserted all the way to the collar. This mitigates any potential frame damage or kinks to internal cables that may result in suboptimal performance.

What is the warranty period?

On all frames manufactured after October 1st, 2022, we offer a lifetime warranty to original owners for manufacturing defects. Please consult our warranty page for further details
