Hey sjt, welcome from over here in Camel City. Interesting to see that you have that Klein. I recently bought that frameset to build up for my son's birthday, after buying my Wilier last summer. This was a first try on my part, took the Ultegra off the Wilier and put it on the Klein, whaddaya know, it works! Then I bought a low-end Campy groupset and put that on the Wilier (had to be all-Italian
), and can you believe it, that works too! Best of luck, hasta la vista.
