INTRODUCTION
Thank you for choosing NS Bikes. We are passing into your hands a frame that has been a milestone in the development of
our company. We have worked on it passionately for well over 2 years, gone through countless prototypes, tested each one
by our team riders and re-worked it untill everything got dialled.
Seeing satisfi ed customers is the biggest reward that we can get for this working hard. So we did everything in our power to
make this happen, but even then, a product that is not properly set up or maintained will be a disappointment. That is why it’s
so important that you acquaint yourself with this manual before your fi rst ride.
We hope that you will be just as happy riding your new FUZZ as we are!
FRAME CONCEPT & INFORMATION
The Fuzz is a true DH machine build to compete with the best in the pits, yet it is still a modern do-it-all rig for any gravity as-
sisted riding. The frame has been raced by our specially assigned R&D team, thrashed by one of the most vicious freeriders
- Jaws, and then fl ipped and whipped by the #1 freestyle rider in the world - Sam Pilgrim. As with all NS products, the Fuzz has
been built to provide the best race-day performance combined with everyday usability and reliability. It’s strong, easy to adjust
and will rip right out of the box.
Geometry: The frame has truly modern DH geometry - it’s low, slack, and has a very short rear end with a roomy front triangle.
Thanks to the adjustable dropouts you can set up the bike with a super tight rear end or you can fi t the wheel in a more standard
position to suit the characteristics for any track and riding style. The short position results in one of the tightest rear ends on the
market. Thanks to this we could really open up the front end and benefi t from massive stability and confi dence improvements,
yet still keep the wheelbase (hence maneuverability) under control.
Suspension: the Fuzz has a clearly progressive leverage ratio curve. The fi rst stage of the travel is very supple and absorbs small
and medium impacts. Towards the end of the travel, the frame becomes sti er, and gives the rider a feeling of support, which
results in predictable launches o jump lips and other obstacles that require getting air to clear. It’s important to note that the
characteristics are di erent on the short and long setting with a noticeably softer and less progressive feel in the long setting.
Kinematics: the 4-bar Horst link suspension has a signifi cant amount of rearward axle movement which helps to absorb square
faced bumps. The system, unlike most other designs on the market (including virtual pivot designs) it is immune to brake jack
(i.e. the torque generated by the brakes will not cause the suspension to sti en). There is also a fair amount of anti-squat built
into the design to counter pedal induced bob. The shock, which is the most heavy part of the frame is tucked away near the BB to
keep the center of gravity as low as possible.
