FRAME DEDICATED FOR SUPER ENDURO
5 star ***** magazine review results in Big Bike
SERIES FOR THE RIDERS BUILDING BIKES ON THEIR OWN
Our fresh new design is dedicated for Super Enduro, mini DH and Freeride with downhill performance of its bigger brother F-44. Redesigned Zumbi FPS System suspension linkage. The F22 was weapon of choice of French slope style and dirt star Antoinie Bizet who got it to many podium finishes, winning such events as the famous Chatel Mountain Style. The F-22 can be built into extreme enduro bike, Mega Avalanche with 170 – 180mm of travel or a more aggressive freeride, mini DH, bike with 180mm travel depending on the shock length you choose. Active suspension under hard braking. Easily adjustable head angle. S-bent swing arm profiles increasing stiffness and crank clearance. Pedal bob free. Super stiff linkage thanks to our pivot axle design.
Optional Ti6Al4V Titanium pivot axles in F-22 Ti version saving weight. High quality sealed ball bearings
Frame without shock

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
- The most unrivaled advantage of the 7020 Alloy frame is its maximum rigidity while maintaining a low weight
- Low weight of Zumbi F-22 frame – 3690g with shock for size (M)
- Innovative concept of mass distribution with low center of gravity gives the possibility of spontaneous reaction, offensive characteristics, agile riding and clashes with bumps
- Owing to the refined pattern of lengths of individual pipes, the rider has the ability to maintain a comfortable body position during a whole day or several days of riding
- Optimally selected angles, allow good control of the bike in the bands and slips
- Carefully selected, aerodynamic solutions optimize: driving dynamics, stability and control of the bike
- We lowered the air resistance by reducing the aerodynamics – improving startup performance and riding comfort
- TTechnology of the force system, combines the sum of internal and external forces acting on the bike while driving, and with the appropriate setting of the suspension parameters, precisely lead the cyclist out from the difficult situation on the track
- The connecting elements are made by ultra modern CNC machines, and their construction, thanks to the appropriate technology and design, influences the exceptional side stiffness of the bike and saves further grams in the frame
- Sensitive elements of the rear triangle are made using inlet technology
- Suspension works in system with a virtual rotation point (FPS). It works in a progressive way supporting the work of the damper
- Suspension is characterized by the lack of influence of braking on its function
- The suspension is designed to increase pedal efficiency while eliminating chain jerking and suspension pumping
- Internal cable lead, a method that guarantees easy servicing and freedom when steering the handlebars
- Tapered head of the frame, ensures better bearing durability, allows the head of the frame to be connected to a larger diameter pipe, which has a significant effect on the rigidity of the bicycle, and also affects the weight of the entire frame
- The 12mm rear hub and the use of a special hook provide the right connection of the wheel hub with the frame, which affects the stiffness of the rear triangle
- Regardless of the painting method, top-quality varnishes are used, providing a fantastic color effect at the same time
- Only aluminum frames are subjected to an electrochemical anodizing process consisting in the production of an oxide layer on the coating enabling the chemical substance to penetrate the coating together with the color into the frame structure, guaranteeing a 100% longevity
In addition, Zumbi Cycles bikes are equipped with the best components from FOX, Cane Creek, BOS Shimano, Race Face, Maxxis, DT.
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 possibility of losing precious seconds during a downhill race and 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.
Thanks to precise calculations carried out in ZUMBI LAB and tests in the field, we created the technology of virtual pivot point, moving on the mathematical calculated curve. The Rider feels as if they were flowing and the FPS system responds to commands and obstacles, as though it was programmed in the bike. Gear ratios are selected so that the suspension from the beginning of deflection has a slightly progressive nature, offering increased sensitivity to small shocks and tactile progressions during high jumps, avoiding a sudden banging. Therefore the FPS system was described by the players of the Downhill World Series ‘a cushion suspension system’
build the FPS system we use our technologies: CNC revolution, FT-7020, FT-parts. Therefore, all four pivot axles in bike are made from high quality materials such as titanium alloy or stainless 6Al4V CrM. All pivot points, rotate on high-class sealed bearings of enlarged diameter or optional ceramic (further reducing weight and guarantee higher efficiency in extreme conditions), 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.
The operation of the system is supported by the damper precisely set and adjusted to the suspension curve. Owing to its appropriate location, we reached perfectly low gravity center -exactly where it SHOULD be – just under the racer. In this way the Zumbi bike is perfectly balanced, stable and agile, which gives a great feeling both while fast singletracks, jumping drops and taking bands.
