So I bought a new bike from DNA one week ago which I payed $650 for. I got two flats the same day not riding the bike hard at all. I bring the bike back and say hey can you help me out. Well I end up getting charged a extra $50 dollars for tubes. I understand they are in the business of making money but c'mon don't think you could take care of me on this first problem! Not only will I not be going back, but I will make sure to tell anyone I ride with what had happened and to not use those guys. Great relationship building DNA and now you have one more person out there to say you suck, cheers.
