NS Bikes Announces New Fuzz 29er DH Bike

The Fuzz has a special place in NS Bikes history. It was our first real downhill bike, and we worked very hard to make sure our debut was a success, so the effort behind this project was massive. We not only wanted performance, but also day-to-day reliability.

It has been to Rampage and has a pretty good record in major international downhill races. The platform has been around since 2013 and during that time evolved from 26” wheels to bigger 27.5” ones, with some geometry updates in the meantime.

Fuzz prototype debut during Red Bull Rampage 2013. 26" wheels, obviously.

However around 2 years ago we started working hard on developing a completely new version of this bike in a close cooperation with our Factory DH Team. One of the obvious changes that we had to make was to put the bike on big 29” wheels. The team riders were really enthusiastic about the concept of racing a 29-er on the oh-so-demanding courses of UCI DH World Cup, so we found a common language, and the work kicked-off immediately.

First ideas of geometry changes.

Basically everyone involved wanted more than just the same Fuzz with bigger wheels. There were much more work to be done, to make the bike even faster. Hardcore bike trashing, being very deep in our DNA, influenced the suspension design of Fuzz 27.5" - it's very progressive and almost impossible to bottom out. Good stuff if you’re after super long jumps and unreal drops.

The new Fuzz is meant for all our racing, so this had to change. The team’s feedback on the 27.5 version (which they have raced in 2017) stated that the bike needs to use the whole suspension travel more, and give more support in the mid stroke. So our main goal was to change the leverage ratio to less progressive than the former 27.5” version. Originally we designed quite a lot of progression into the suspension, keeping in mind that our bike would be used primarily for hucking and bike parks.

Fuzz 27.5 vs Fuzz 29 - leverage ratio and anti-squat comparison.

Secondly, the riders opted for more anti-squat to keep the rear suspension from bobbing, while pedalling hard on the flatter sections of the course.

The new kinematics resulted in a more compliant and predictable feel in the mid stroke and promotes the use of more travel. We achieved that mostly by redesigning the main rocker from a previous 2-pcs to a much stiffer single piece monolink (we were also able to drop the seat stay bridge - making more space for big wheels) and revising the dropouts.

We continued to use the custom offset headset, known from the 27.5" version, which allows the rider to adjust the reach of the bike, choosing from 3 positions: -8mm, zero, +8mm.

The initial rides on the first bike samples confirmed just about everything that the theory assumed. The 29-er rides faster on virtually any type of courses. Maybe except very narrow and twisty tacks, however its cornering abilities were also improved by lowering the BB by 11 mm.

The feedback from the team was very positive, so there were no doubts about which bike to choose for the 2018 season.

The Fuzz 29” was one of the first big wheel racing machines in the World Cup pits and tracks (which makes us very proud). This year it’s also hitting the shop floors in not-so-racy graphic design (that’s how we like it). The bike is equipped with Fox Factory 49 Float Grip 2 fork and Fox Performance Elite DHX2 rear shock. It rolls on our new Enigma Rock 29” rims, designed specially for heavy-duty downhill applications.

 i like the look of this bike.. Very much.

 Absolutly, ready for some good sessions!

 Perfect for the world's roughest treks.

 the Raw finish looked better than the production one!

 always does Wink

 But that floating hand on the back tire is creeping me out.

 @masonstevens: Thats Thing. From the Addams Family. Dont worry, he's cool.

 @masonstevens: I can't find it and feel left out. I do see a rubber band on the rear hub that is weird, but I don't think that's what you're talking about.
  • + 8
 5599,- for an alloy frame, X2 performance, NS own handlebar, saddle, stem, seatpost, wheels, Code R, SRAM GX DH and two sizes, only?
Where does this price come from?
I really like the looks and the performance seems to be good, as well, but value for money is something different, IMHO.
  • + 1
 And the outer casino of the derailleur on top of the chainstay? Like... how often does NS expect the customer to replace the casing? Every three weeks?
Plus, it doesn't even run straight over it, but on its side and then back to the attachment point?
Did they forget about this, and haven't had the time to design this properly?

 It is an NS so wait 5 months after they are released and pick one up from CRC for 55% off, like everyone does.
  • + 3
 Probably worked it out on the other side of the paper that the geometry changes were drawn on.

 NS bikes have always been way overpriced.

For example: www.chainreactioncycles.com/ca/en/ns-bikes-fuzz-2-dh-bike-2019/rp-prod172299
Boxxer RC,Ruktion crankset, X5 shifter, X7 derailleur, Guide RE brakes, everything else is NS owned
ON SALE for $5,100 CAD...

Meanwhile: www.chainreactioncycles.com/ca/en/vitus-dominer-dh-suspension-bike-sram-gx-dh-2018/rp-prod159736
$2,800CAD and almost(if not) better components in every way.

 I prefer the crayon diagrams over cad. Just saying.
  • + 9
 Yes! Kinematic charts need to be standard for every bike release. Good on NS for not being coy. Wish they'd also give us the AR and PK charts but those are less valuable than the LR and AS charts anyway.

 i got downvoted into oblivion for politely suggesting it in the gt fury release - so i bring it up again
  • + 10
 5599€? C’mon.
  • + 2
 Got to try one for a day end of last season, easily the fastest dh bike I have ever tried. And the first that felt like it fit. Since I'm 194cm almost all dh bikes are to short. But this in large, set in long position was not bad. Scary fast bike and worked surprisingly well on tight trails.

 Gotta love the intentions of a bike that ships with a no nonsense coil shock and double Magic Mary's.
  • + 3
 What are the intentions of a DH bike that ships with Enduro tires?
  • + 5
 @Rubberelli: downduro mate.. its a new game

 The Fuzz is a great, well rounded, dh bike. Sure, it’s a little heavier with an aluminum frame, but it’s a downhill bike. Watching a WC Dh bike ride the Rampage is a testament to its versatility, durability ( see aluminum frame) and good design.

 That, that is a wagon. I got all excited seeing it's in metal instead of carbon too. Times, they are changing.
  • + 4
 This is a really good looking bike......kudos NS
  • + 4
 Nice job NS. That is a beautiful bike!
  • + 3
 I agree with his approach on reach values. The current method really doesn’t portray the actual feel of the bike as well
  • + 3
 This bike is beautiful the frame lines and the way the shock is mounted Drool
  • + 3
 This is WAY more interesting than all the AXS release/press bomb.
  • + 2
 Not a fan 29er but bikes looks really nice Smile
  • + 2
 It has been on their website for at least a month.
  • + 1
 Yes, nice looking bike. But again, its overprized. Alu frame,GX, 17kg, 5600€? This industry is beyond reasonable.
  • + 1
 well it looks like a session
  • + 1
 This bike would look really rad in blingy chrome!
  • + 1
 Best new rig
