A certain Danny MacAskill brought street trials into a new dimension in 2009 with his incredible video. 24” opens new perspectives for the sport, bringing more manoeuvrability and flow and making tricks previously only seen in BMX to be pulled on a trials bike! Last year 24" bikes began to be seen in the sections as well as on the street, with a whole series of rock-hungry bikes hitting the market, some of which Tribal Zine tested in May (24" Test). We were excited by this new phenomenon which seems to have rejuvenated our sport: the 26” riders rediscovered bunny hops and more technical moves and the 20” riders enjoyed the improved rolling ability. 24” are very playful and effective and we think they have a very bright future ahead of them, especially as they are an excellent transition bike between 20” and 26” and an accessible way of getting into the sport.
Bruno Arnold and his team, who very quickly realised that 24” was not a mere fad and that it appealed to competitors/natural riders and street riders alike, have been developing two 24” models for several months: the street orientated “King of Dunce”, developed by Yohan Triboulat, and the ‘pure’ trials model, the “Unruly”. These frames were recently presented to us and were even available to try at the French Cup in Méribel.
The frames have arrived in France and are already available from Sphère Bike! More info on the Ozonys.
The King of Dunce :
Le King of Dunce, is the rebel of the Ozonys 2011 range. It is stylish and robust, with a street-specific geometry to make tricks, spins and general chucking about that little bit easier. Reinforcements have been placed in all the right places so that the frame is rigid and resistant to the forces that it will be subjected to. Chain tension is taken care of y two bolts at the front of the dropout and the frame has both HS33 and disc mounts – one of the advantages of 24” wheel is that discs work very well. The 6061 Aluminium frame is light (1690g) and reasonably priced (€390).

The Unruly:
The Unruly, the most recent addition to the Ozonys family, adopts a geometry that is fast becoming the standard for the more ‘trialsy’ 24”s, has large, well-placed reinforcements and a classy, almost retro look with the relatively chunky seat tube, grey anodised finish and snazzy graphics. The 6061 Aluminium frame is light (1690g) and reasonably priced (€390).
