I don't think the Roubaix FI is available any more - AFAIK it's a choice between the TK434 and the TK607 for Assos 3/4 knickers. I've got a couple of pairs of the TK434 for keeping my aging knees warm, and bloody nice they are too. The only oddity I find is that while I'm a size large in Assos shorts, I'm an XL in 3/4s and bib tights. But no hesitation in recommending the TK434s.
