Me :-) The brakes are crap, both wheels need to be trued (which won't happen until I get a truing stand), and the fork is crap as well (95 mm pivot spacing and one leg farther from the center than the other, resulting in having the wheel a bit off-center & making it a PITA to adjust the brakes), and the saddle clamp doesn't hold the saddle very well (I have a spare one, will use it soon). Also, the I got the pedals (Kona Jack****) used which meant having to rebuild those as well...

However, I was surprised by the weight, I expected it to end up being way over 15 kg without the accessories.
