THE HISTORY OF MTB FRAMES
Next year we will have celebrated the 20th anniversary of Zumbi Cycles in Poland. On that occasion we would like to present in our article the range of past models of the Zumbi frames to show you the characteristics of those days. Was our approach innovative?
The Zumbi frames are becoming real collector’s items. Should you have the models from the old times, do send them for renovation in order to increase their value. Please contact: firstname.lastname@example.org – to do okna mailowego
In 2019 a big auction event will be organized. Not only will you be able to resell your model but also purchase the dream one. Stay tuned for more info FB
ZUMBI DH Team – Downhill – 26’
I (2001) II (2003-2004), III (2005)
Race proven downhill racing frame hand made and cnc machined in Poland from 7020 alloy. The swing arm is built from 6 separate rectangular profiles welded together. It uses two huge, 40mm high quality sealed ball bearings and a 20mm pivot axle made of Ti 6Al4V titanium (DH Team Ti) or high grade steel (DH Team).
Very low center of gravity providing superior traction. Two shock mountings changing the suspension characteristic. Braking forces isolated from suspension thanks to our new floating brake caliper which is a standard feature. The suspension path helps suck up those square edged bumps, which slow you down. Super stiff swing arm makes sure the bike goes where you want it to go. The head tube has two gussets and a; enforcement making sure its always in one piece.
I (2005), II (2010)
Designed for World Cup level Trials. Hand welded and CNC machined from the best quality 7020 tubing and billet. Super lightweight. Headtube secured by a pair of gussets. Frame was designed and developed and tested in cooperation with one of the best trials riders in the World, Zumbi Team rider Karol Serwin, 10th at the World Championships in 2009 and classified 9th overall in UCI 2009 listing.
I (2006), II (2008)
Zumbi 4XR frame is dedicated for 4X racing and slopestyle. Designing and development with French mountain bike superstar Romain Olmos effected in an ultra light frame with a very wide destiny. Unique concentric floating shock CFS suspension system designed by Zumbi. Suspension can be set to 100 or 120mm travel easily with an allen key. Chainstays made from four separate tubes welded together resulting in an ultra stiff and reliable design. The concentric BB pivot makes the frame singlespeed friendly. Shock is compressed from both sides in a progressive rate preventing harsh bottoming. Shock air spring pressure is set not only to riders weight but also to rider’s style. Higher pressure for 4X racing where pedal efficiency is most important and the suspension works only when the riders makes mistakes on the new style hard core 4X racing tracks used today, Lower pressure for slopestyle applications. All pivot points use high quality sealed ball bearings. Custom made stainless steel bolts. Bos Suspension provides a specially made 120mm fork specially made for the 4XR frame. Easley built into a 12kg race ready machine.
I (2005) II (2009)
Hand welded and cnc machined from 7020 alloy. The geometry is ideal for 4X racing and dirt jumping. The VooDoo works great as a light freeride hardtail. Using a unique welded double profile chainstay construction and s-bent seatstays greatly improves the VooDooís lateral stiffness. The dropouts and chainstay yoke are pressed into the profiles before welding. Designed to be used with a 100-130mm suspension fork. Replaceable hanger. Headtube has two beefy gussets and a ďwrap around reinforcement making it bombproof. High quality powder coat paintjob. You don’t need black magic to be in front of the 4X racing pack. You need a VooDoo…

I (2009), II (2010), III (2018)
Innovate or die as they say…
Our new line of battery powered electric motor mountain bikes are a result of cooperation with Swiss genius Jurg Lanz from Boosty.ch. Jurg worked over the past 5 years on an innovative idea using his cnc machining and electronical skills to bring to life the most powerful and lightest electrical bicycle motor systems available on this planet.
These bikes can get You to the hardest to reach terrain making possible to climb steep non lift assisted slopes even on a fully built downhill bike! This concept opens up unlimited horizons to the widely named freeriding and exploring. We developed four models using the Boosty system. The E-44, E-22, El Voodoo, and El guru. New is silent motor chainring making the whole system silent. More information on www.boosty.ch
