been quite amazed by OGs new prototypes, especially the Dadan. Furthermore
considering the debate about this one on various flatland forums, we wanted
to do more than showing pics of the frame in the news. So we thought that
an interview with Mr OG bikes, OG Marton (who designed all the parts)
would be interesting and could bring answers to riders who ask themselves
questions or are still unconvinced by this new concept.
people compare the Dadan with some road
or some old school moongoose
design, have you been directly inspired by this kind of bikes
or did you just imagine the Dadan while searching a more effective
design for a flatland frame?
a year ago I drew many "stupid" looking flatland frames.
I was wondering how I could design a frame that can give even more
space to the riders. One of them was the Dadan, but I wasn´t really
interested in it. In the beginning of this year I was talking about
my ideas to Peter Sarlos, Adam Kun and Zoltan Barta (Zoltan runs
the BMXmag.hu website). I explained my idea about a frame (it was
the Dadan but without a name back then), and the guys were stoked
on the huge spaces and pushed me to start working on the real design.
I told them that the geometry looks like a cheap MTB frame, and
would hate it. But the guys gave me motivation to work on it, and
advised me to not pay attention to what people would think about
the looks. It is all about the function and the idea, plus the stiffness
of the frame at the same time. After the Worlds many people came
to us and said that they were stoked on the frame design, and the
Dadan could give them the opportunity to practice tricks that they
just could never do on a regular frame.
of the riders who dislike the Dadan say that it wouldn´t be strong
enough, in a general way, what can you tell to people who don´t
believe in its strength?
production we are going to test all the frames, and change them
if necessary. The OG Bike Company never sold weak products, we
are always taking care of the highest possible quality. (Just
look at the OG Griptapegs and our older frames, no one had a bad
experience with them) You just cannot compare this frame to a
weak mountain bike or an old racing frame made of crappy tubing.
We use the best manufacturer of the industry, so we would like
to let everybody know that the frames will be of a really high
quality and good durability. For the prototypes I intentionally
chose thinner main tube than the ones that we are going to use
for the production line frames. The reason why I did that is that
I´d like to see the cracks and the weak points of the frame as
soon as possible. The cracks show the weak points of a thin-walled
frame, so you can adjust the stronger wall thicknesses. It´s important
for the final version, and it has to be available soon for the
riders. We do not have time for like 5
different prototypes. I think the final weight will be between
2.35 and 2.4 kgs (5.17 - 5.28lbs). For the production line we´ll
use a special Sanko main tube, a single butted one with thicker
wall at the critical points.
How long have you been working on this
design? Can you tell us how many prototypes did you made before
the final version?
complete frame design took me about a week. Usually we only need
to order prototypes only once since we try to use the perfect
wall thicknesses and materials. After testing we know what to
change if necessary. Maybe for the Dadan production we´ll need
one more prototype, but I´m not sure about that. As for the built
up bikes, We really love them. It took a while until we got used
to the looks, but could ride them really well at the first time
of testing. Especially Adam was freaking out. He really loved
the first occasions of riding the Dadan, and likes it ever since.
a 74.5° head tube angle? Did you chose it after various
tests on angles or because of the actual evolution toward
"chopper frames" in flatland?
the past most of the frames featured 74.5° head angle,
and some of them were even more "choppers". For
whiplashes, g-strings, and pinkies they´re very useful.
For fast switches when you whip the frame around it´s also
very good. For example when you do whiplashes, your rear
wheel´s space is bigger between the ground and your tire´s
bottom point. It means you have more balancing possibilities
without touching the ground with your tire. In the early
90´s I learned g-strings and whiplashes with a Homeless
Soul Bro frame, and I loved that one. That bike was a real
chopper, I can´t remember the exact head angle. Anyway,
you will feel the difference.
an optionnal Spanish b.b. on the Dadan? Do you think it
is the upcoming standart?
not really happy about the upcoming standards, especially
when I hear many problems about the internal headsets. If
the bearings are not 100% parallel inside your headtube,
then your bar won´t turn around smoothly and/or will be
loose at some points. I still like the EU BB and the regular
headtube, they won´t bring too many troubles. Spanish and
internal must be available if riders like it, but I´m not
really into them!
riders wonder why OG dropouts are shaped differently as
other frames can you explain the reasons of this design?
slots on the dropouts are always parallel with the ground,
if you change the rear wheel´s position it won´t effect
your headtube angle. We also care about the necessary space
for the pegs, trying to save power on the axle.
the Dadan and GypoII tests over? If yes, do you already
know when the new OG products will be realeased?
need a little more time for the final results, and think
that the new products will be available within the next
2-3 months. The Gypo2 is a perfectframe, I do not think
we need to change anything on that one. So are the handlebars,
they feel so nice.
you already tell us what will be the price of the new OG
frames will be between 250-299 Euro, the Caramel bar (in
two sizes: 7.36" and 6.5") will cost around 90
