I also tried to contact BWW a week ago regarding tech questions on their in-house line of rims and hubs. I got a funky answering machine message and didn't hear back from emails. They have built wheels in the past for me that were a good set and I was pleased wiht the performance. Although not hearing from them "kinda" concerns me, I threw caution to the wind and ordered a set of ultegras with mavic rims. This Friday will be one week the order was placed. Hopefully there still in business and lacing up the wheels.
