Last weekend, the traditional BangKing was arranged in Japan, in which everyone could enter.
Unfortunately, I could not take part on it personally, only as a sponsor; but it was good to see the smile of Matsudos face, who had Yobi hubs in his hands!

“Providentially, the Uchinada velodrome in the prefecture of Ishikawa (along the coast of the Sea of Japan) hosts designated periods when it is open to the public. As the weekend training sessions of the professional riders stamp the authenticity of this bank, this arena provides the perfect opportunity for us city track racers to experience part of the keirin world.”

BangKing 2010 in Japan

After the Hungarien Track Championship Szalontay Sándor and Veres Ádám competed again in Prostejov.
Remember… Sanyi and Ádám wins 3 gold medal a few days ago.
At that time they was very convincing… unfortunately in Prostejov the enemy was too strong, yet..

After the first testing day of the Kalavinka frame I can state that it performs beyond expectations and also works perfectly together with yobi bike parts!
The whole construction is extremely rigid and very demanding, well done Kalavinka!
The “K” letter at the bottom of the carbon fork is truly a masterpiece!

Both the eccentric technology and the chain stay’s bending are very smart solutions.
The only disadvantage could be the weight, but in every other aspect it’s better than the previous ones!
The distance of the bottom bracket from the ground is 295 mm (it’s a good one, thanks to the eccentric solution).
The axle-distance is between 940-990 mm( size-L), is short.  The bb axle-rear axle distance can 370 mm. It provides a really good acceleration factor.

And a few things about the wheels:
I’m totally satisfied with them! The two-cross-style makes the rear wheel very strong and it spins awesome.
Just watch the national tricolor stripe spinning at 70 km/h!!!

‘Mama’ and ‘Papa’

During the last few weeks I worked hard to redesign the hubs.. to have a clearer and simplier design.
I think the result speaks for itself. I changed the fixation technology of the old version to replaceable high flanges.

here you can see more pictures  about it.

I also developed a pair of more conventional hubs.
Both variations will be available within the next few weeks.
For more details, please contact me, thanks!
