Nashbar and Performance have been the same company for a few years now...they just market to different people. Nashbar has the same ones. Most Nashbar brakes are Tektros and thier bars, stems, and seatposts are Kalloy.

Their $5 cheaper and in stock! (Since I have the tape off my bars, perhaps I'll spend the big bucks.....)
