SERIES FOR THE RIDERS BUILDING BIKES ON THEIR OWN
It all started with an idea for building the ultimate “enduro” frame. The F11 29er frame was created in new Zumbi factory.The main concepts of the F11 were the connection of super active, brake force isolated suspension with great pedal efficiancy. To find the ultimate compromize between all three was tricky and over the years the frame evolved step by step. Boost 148x12mm or standard 142X12mm dropout spacing. Tappered headtube. New CNC Parts,
Worlwide race proven in the Enduro World Series geometry, built around leading suspension guru, Float pivot suspension system makes this frame the ultimate ride which will handle the roughest terrain when exploring the Worlds best trails.

TECHNOLOGY OF ZUMBI BIKES „F” SERIES
- Zumbi frames are 100% made of uniform, expensive and most durable aircraft aluminum 7020
- No interference in the structure of the material, ensures its originality and ultimate durability
- Light-weight Zumbi F11 frame 650b – weights only 2800g (size “M”)
- Innovative concept of weight distribution with low center of gravity, helps in spontaneous reaction giving geometry an offensive characteristics
- Tanks to the defined length patterns of individual pipes, rider has a possibility to maintain a comfortable body position during a whole-day ride or longer several days adventure
- Optimally selected head- and seat-tube angles allow perfect control in the slippery corners
- Carefully optimized aerodynamics performs stabile and forceful bike path
- We scientifically lowered the air resistance of our bikes improving startup performance and riding comfort
- Power distribution technology combines the sum of internal and external forces affecting the bike while riding, precisely leading the cyclist out of the difficult situations on the trail
- The use of CNC parts influences the exceptional side stiffness of the frame and allows to save some extra grams
- Sensitive elements of the rear triangle are made with use of the inlet technology
- Suspension is based on a system with a virtual swing point (FPS). This supports progressive way of the shock’s work
- Suspension characterize full isolation from the forces coming from pedaling and braking
- The suspension is designed to increase pedal efficiency while eliminating chain-suck and shock pumping-up.
- Internal cable routing guarantees “clean” frame design and maintenance-free structure
- Tapered head-tube ensures increased bearing durability, allowing the a larger diameter steering tube, which has a significant effect on the rigidity of the bicycle’s front-end
- The use of a specially designed drop-outs provide superb connection between the wheel hub and rear frame’s tubes. This affects the stiffness of the rear triangle
- Regardless of the painting method, top-quality varnishes are used, providing an extremely vivid colors
- Only the aluminum-made frames are subjected to an electrochemical anodizing process. This produce an oxide layer over the coating, enabling the chemical substance to penetrate the frame structure together with the color, guaranteeing a 100% longevity effect
In addition, Zumbi bikes are equipped with the best components from FOX, Cane Creek, BOS, Shimano, Race Face, Maxxis, and DT Swiss.
Floating Pivot Suspension System
Full suspension – for the best riders
The passion for precision combined with years of cycling experience contributed to the construction of one of the world’s best mountain bike suspension systems- the FPS System. It uses four, perfectly calculated, pivot points that determine the initial and final leverage ratios. The FPS System stays fully active and isolated from braking and pedaling forces even on very hard terrain. It reduces to the minimum the threat of losing precious seconds during a downhill fights for the podium. The system is used in the following Zumbi Cycles frames and bikes: F44 27.5-inch (downhill); F22 27.5-inch (super enduro); F11 650B/27.5-inch (enduro / all mountain); F11 29-inch (trail / tour); as well as ZUMBI – BOSH E-BIKE and PINION system ones. Kinematics Thanks to precise calculations carried out in ZUMBI LAB and tests in the field, we were able to create the technology of virtual pivot point, which follows the mathematically calculated curve. FPS system responds smoothly giving the feel of flowing to the riders. Gear ratios are wisely selected so the suspension from the beginning of deflection has a slightly progressive nature, offering increased sensitivity to small bumps and tactile progressions during bigger jumps. Therefore the FPS system was described by the players of the Downhill World Series as ‘a cushion suspension system’ Technology To build the FPS system we used our reliable technologies: CNC revolution, FT-7020 and FT-parts. Therefore, all four pivot axles used in our bikes are made of highest quality materials such as titanium alloy or stainless 6Al4V CRM. All pivot points swing on premium-class sealed bearings with oversized diameter (ceramic bearings reducing weight and guaranteeing higher efficiency in extreme conditions are available as option) thereby increasing their strength and vitality. FT-7020 technology is used to build the frame connectors, precisely cut from a block of material by CNC tools. (See CNC revolution) All these elements influence the extreme stiffness of the frame, which results in precise control of the bike under extreme overload. C.O.G. The operation of the system is supported by the precisely set-up shock, naturally following the suspension curve. Thanks to its innovative location, we reached perfectly low gravity center – exactly where SHOULD it be – just under the racer. All this make the Zumbi bicycle a perfectly balanced, stable and agile singletrack killer. Our video tutorials and training sessions will show you how to set the suspension parameters.
