Indeed it looks like a further development of the 168 frame. If so, it is not, as usual, a replica of western bicycle manufacturers. I wonder if it is really their own design?

Damn. This is a serious issue. I was seriously contemplating purchasing one of these framesets. Too many issues to be sorted yet. Any attempts to rectify the problems just seem to be mostly lip service from VB.

I think most problems are caused by unskilled assembly of the bike or can be solved with a clever work around. In my case the customer support of velobuild assured me to send a bigger compression ring, which should solve the problem.
In general I never heard of serious structural problems with these frames. Considering the low price of the frame set, you can get very good value for money. On the other hand, you have to be prepared to find your own solutions to solve problems. If you want a road bike, which works "perfect" in every aspect, you have to spent MUCH more money. So, If you don't have a problem finding solutions yourself, I can really recommend the frame to you.

Hi all,
I finished my build in june and have driven it 1300 km since then. I really like the bike in general  . Luckily I am one of the persons without one of the common quality problems, beside the following issue.
As some other guys i have to use micro spacers, to get get enough space between the top cover of the headset and the head tube. Otherwise the top cover would touch the head tube when compressing the headset.
Unfortunalely my microspacer arrangement slips out of place form time to time, which leads to a loose headset. I attached two photos, to illustrate the problem.
Maybe you can share picutes of your microspacer arrangement or any other advice on how I can address the problem would be very much appreciated. thanks in andvance
