Everyopne has their opinions.
They may not have the 'neatest' welds, but they're fit for purpose. Bike geeks are a funny bunch. 'Rubbish welds' usually mean they might not have a symmetrical pattern or look pretty - after all, how many typical bike nerds are metal fabricators? Don't know their arese from their elbow most of them, its just knowledge picked up from hearsay, LBS and the internet. In this day and age, LBS's don't really know much better than the rest of us (i.e. the buying public are better informed)
I've had a couple of on-ones. The fabrication has been fine as has alignment. They've modern geometry, arguably at the forefront of modern frame geometry thinking and not afraid the experiment. They've ridden pretty nicely to, but the paint is brittle and poor wearing.
Its a bike build to be competent, with sensible materials as cheap as possible (in relative terms) can't see a problem with that myself.
Its never going to be a curtis is it?
