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 satisfied 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 first 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 built to compete with the best in the pits, yet it is a modern do-it-all rig for any gravity assisted
riding. The bike has been thrashed by Sam Pilgrim at events like Rampage and proved itself in the real racing environment too,
taking podiums at major UCI events, piloted by the Polish DH star Slawek Lukasik. The frame has truly modern DH geometry - it’s
low, slack, and has a very short rear end with a roomy front triangle. The 4-bar Horst link suspension has a significant amount of
rearward axle movement which helps to absorb square faced bumps. Unlike most other designs on the market (including virtual
pivot designs) it is immune to brake jack. 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 centre of gravity as low as
possible.
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 fit 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 benefit from massive stability and confidence improvements,
yet still keep the wheelbase (hence manoeuvrability) under control.
Suspension & kinematics: the Fuzz has a clearly progressive leverage ratio curve. The first stage of the travel is very supple and
absorbs small and medium impacts. Towards the end of the travel, the frame becomes stier, 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 dierent on the short and long setting with a noticeably softer and less progressive feel in the
long setting. The 4-bar Horst link suspension has a significant 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 stien). 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 centre of gravity as low as possible.
