I have it on good authority from a Serotta and Bohemian Bicycles trained frame builder that quality control of Baums can be improved. I'm sure thy are nice bikes, but maybe you could do better?
Name a brand that is perfect.
It's no secret I worked for them. Darren and I are mates but I owe him nothing. If his bikes were rubbish I'd sell them. Mistakes get made, mistakes get fixed. It might sound cliché but being handcrafted means that human error can occur. But then even mass produced bikes have faults and 'quality control could be improved'.
Funnily, you don't see Baum owners on here smearing other brands - like Serotta or Bohemian. I wonder why you (and those brands) feel the need to behave that way? Myself and almost anyone who has worked in the custom bike industry will have seen examples from other brands where it could have been done better. Only we don't air our dirty laundry. Guess that's the joy of being an anonymous account on the internetz. Unless your name is David and you are, in fact, quite lonesome.
