I got the same bottom bracket and it worked great. For my next projects I want to get a bottom brakcet with a square taper spindle, mainly so that I am not locked into either GxP or the Hollowtech systems. IRD has something that seems like it would work. I would post the link but I am still a newbie so I can't post links but you they are called "IRD Bottom Bracket Conversion Cups Pair" that work with their QB-55 bottom bracket. I am not sure it will be compatible as IRD seems to mainly make MTB parts but I think that I will give it a try. Velo orange has some deceptive bottom brackets that I thought would work but like I said, the bikes I have been working on are swiss threaded and the french bottom bracket on velo orange had the wrong threading.
