Did 140km on the Kocevlo bars today and they felt great - shape of the bars is good, flats on the top feel very comfortable and basically no noticeable flex when I'm putting an effort in.
Sounds great, i am also thinking about getting those bars!
You mentioned that a sticker is easily removed. Are you talking about that white "Kocevlo" branding? that was actually holding me off from placing an order since I always read "Cock-Velo" 
So great news, if that can be removed without residues.
And are the measurements true to size in your opinion? E.g. Hood/Drops width, reach, stem length, angle? I read a lot of contradicting statements regarding that barstem (from different manufacturers)
Thanks!
Yes, I'm talking about the white 'Kocevlo' sticker. I could mostly peel it off with my fingers and the residue came off easily with some acetone.
As for measurements, I have taken some very rough measurements just with a measuring tape by eye:
| Specs | Actual | Difference
----------------------|---------------------|--------------------------------------------------------------|-----------
Stem Length | 100mm | 110mm (+10mm longer) | +10mm
Tops centre-to-centre | 380mm | 380mm (right on) | 0mm
Drops centre-to-centre| 400mm | 405mm (+5mm wider) | +5mm
Reach | 77mm | 70mm (-7mm) - measuring accuracy uncertain | -7mm
Drop | 127mm | 130mm (+3mm) - close enough, could be measuring error | +3mm
Weight | 520g±20g (full pkg?)| 330g (bar/stem) + 30g (Garmin mount) + ~25g (spacers, est.) | -135g
I don't have a way of measuring the angle but it looks about right, I guess.
I have the same bars on my Hygge bike. I had no problems routing the 4 cables (brakes and shifting) trough the handlebar.
Excellent! Maybe it's a matter of slight differences between bars, slightly different dimensions and I expect my fairly upright shifter position probably means there's a little less room for cables after they exit the bars (see pictures).
