Prolly was consulted. The bar ends were machined at BMW, and designed by Supermighty aka EddieBrannan who is an occassional poster on here. I saw a set a BMW when I picked up my new frame on friday. Pretty funny.
On a side note, an awesome shop. BMW not only builds all of thier frames in house, but they also machine every part of thier jigs in house. Top to bottom, all made right there. Pretty rad if you ask me. Thier stems, barends, seatposts, pedals are all made right there too.
And if anyone is wondering, thier gangsta is awesome. I have rode the hell out of it the last few days, a great bike for city streets.
