I own a 268 - one of the first I guess, since then there were some changes in the handlebar and fork (i like my handlebar..)
The quality of the frame is hard to tell just by eye
What I could see from the inner parts looked very neetly manufactured.
There's a German bike selling company, that sells Workswell frames also one of the gravels. "Racextract" is their name.
And "benotti" bikes sells the 268.
From my side I am very happy with my 268. Has 2000km on the road and almost 10000km on the power trainer. Since it didn't collapse right now, I guess that's a good sign. On the road I hit some very bad pottholes and nothing happened.
Guess they are not the cheapest around... but I don't remember exactly how much I had to pay. Roughly 1000€ for frame, handlebar, seatpost, headset, chameleon paint, shipping and taxes. But that was in summer 2019....
The chameleon turned out to be much darker than expected from the photos.. this is maybe the only thing that is not perfect .
Instead of purple gold it's black with slight purple gold shimmer on top..
