It is no secret that Nukeproof have been developing a new downhill frame. For some, it may surprise you that it’s not out already. It’s taken riders to a world cup podium, raced at Red Bull Hardline and even made it to the top step at the Crankworx World Tour Downhill.
Since the prototype carbon frames rolled out at the UCI Downhill World Cup in Fort William, the Dissent Carbon frames have undergone a year of extensive testing and development by the world’s finest downhill athletes. This bike is purpose-built to handle the speed and pressure of world class downhill racing, and no amount of private testing can serve as substitute for the real thing.
The carbon Dissent prototype has been hugely successful, too. During the 2022 season the prototype frames racked up numerous podiums and victories on the world stage. Most notably, Louise Ferguson at Crankworx New Zealand and the incredible UCI Downhill World Cup podium with Ronan Dunne in Snowshoe. The frames faced the ultimate test of strength at Red Bull Hardline coming away unscathed in the hands of Ronan finishing 4th, Adam Brayton 12th and Chris Cumming 18th. These prototypes have been tested thoroughly and tested hard.
Since the Nukeproof Scalp was debuted in 2011, Nukeproof’s downhill frames have been on a constant evolutionary path. The Scalp saw success at the highest level, eventually evolving into Sam Hill’s World Cup-winning Pulse. This evolution continued through to the latest Dissent.
Using an evolved version of the Nukeproof Fallout linkage, the Dissent prototype frame won first time out with Sam Hill at the Garbanzo Downhill at Crankworx Canada in 2018. Since then, the Dissent has gone on to rack up a number of UCI World Cup podiums and national championships. It’s earned a reputation as a race-ready workhorse that’s incredibly stable and ultra-adjustable; as a bike that instils confidence in world-class pros and privateers alike.
Nukeproof are proud to release the latest evolution-the Dissent 297 / 290 Carbon.
SO WHY CARBON NOW?
Like many decisions in Nukeproof HQ, it was not commercially motivated. Some after-hours concept sketching of what a potential carbon Dissent frame could look like, whet the appetite. The sketches looked so good, it just had to be made.
Creating a carbon Dissent gave Nukeproof engineers the freedom to make several improvements, as well as incorporate some new features into the frame. Having the freedom to work in carbon allows for more complex shapes, fast multiple prototype iterations to add strength, stiffness and compliance to enhance the feel of the bike. The reason to move wasn’t to reduce weight, but the overall frame weight was reduced by430g. (a NP1 frame weighs 3.46kgs RAW)
The Dissent Carbon now includes numerous methods to dial a perfect fit.
- Three Frame Sizes: NP1 / NP2 / NP3
- Adjustable Headset: -6mm / 0mm / +6mm
- Adjustable Chainstay: -5mm / 0mm / +5mm
The Dissent Carbon offers a vast amount of adjustment, really allowing riders to dial in a reach and position on the bike to perfectly suit them. With the wheelbase flipchips, riders can easily adjust wheelbase trackside to suit various terrains and racetracks.
UNCOMPROMISING SUSPENSION PERFORMANCE
A design originally conceived to test different leverage curves with our athletes, the Dissent Alloy used flip chips to adjust progressivity across four positions. The new Dissent Carbon takes this to the next level, evolving to make altering the positions easier. The Dissent Carbon features three positions that can simply be adjusted on the fly with no need for separate flipchips.
All three settings have a high beginning leverage rate to make it super supple off the top yet offer good consistent mid-stroke support with a regressive end-stroke to prevent spiking under bottom out. The new Dissent Carbon adds a degree of sensitivity to the beginning of the stroke, this allows riders to go up a spring rate without adding harshness and works much better with the new generation of air shocks. Going up a spring rate is usually preferable to more compression damping as it suits fast riders and prevents spiking that could otherwise lead to punctures or damaged wheels.
