In my opinion...yes. Both frames are well made, are name-brand tubing, and "track" geometry. Moreover, the Rush has a 4-5 year warrantee. When I bought my BK, I asked about a warrantee and their response was, "It won't break". F that. Get the Rush. I have heard that the BK has a stiffer BB, but who knows if that is really the case. At any rate, either frame is plenty stiff for what most people use them for.
