Supernought technical specifications can be found on our Tech Support page in the “Supernought Technical Specifications” Download

We recommend 28-30% sag. This equates to 21 – 22.5mm of shaft insertion.

Frame kits include 27.5” and 29” ‘0’ position dropouts.

S1 ships with 300lb/in, S2 350lb/in, S3 400lb/in and S4 with a 450lb/in

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).

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

Complete bikes only come with the dropouts that coincide with the wheels the bike was purchased with.

Yes, Supernought V2 frames ship with ‘0mm’ position dropouts for full 29 and MX set ups. +/- 10mm for MX and +10mm for 29 are available separately.

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

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 611mm

2.6” (maximum width of 66mm at the widest part of the tread)

Supernought is optimized for all downhill specific close ratio drivetrains.

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

Supernought is designed as a downhill bike.Therefore there is no internal routing through the frame for dropper post cable and housing.

Supernought uses SHIS spec ZS49/28.6 upper and EC49/30 lower cups.

Supernought uses a BSA 83mm threaded bottom bracket shell.

Supernought uses standard boost rear hub spacing, 148mm. Standard boost spacing with an 83mm BB spacing provides an optimal chain line for the more outboard, small range DH cassettes.

On all frames manufactured after October 1st, 2022, we offer a lifetime warranty to original owners for manufacturing defects.

This is normal. The water bottle cage is aligned to the centerline of the frame. The shock, shock tunnel, and linkage are offset to the non-drive side of the bike. Because of this, the downtube is not symmetrical along the frame centerline.
