Compatibility of FSA chain rings and Dura-Ace crank.(3 posts)

Compatibility of FSA chain rings and Dura-Ace crank.Ryan
Jan 14, 2004 7:21 AM
I am thinking about purchasing a set of FSA (50-38) chain rings to replace my Shimano Dura-Ace chain rings (53-39). I just have a couple of questions before I make the purchase. 1) Are the FSA chain rings compatible with a Dura-Ace crank (Crank and chain rings are both 130 mm bolt diameter.) 2) How will the FSA chain rings compare in terms of performance (specifically shifting) with the Dura-Ace chain rings.

Thanks in advance.

I've got a black set of rings. None of that flaking of the coating on these babies!

Seem to shift fine, but then I've never really thought too much about front shifting.

the 130mm bolt circle is the same, and the spacing between the rings is the same or within .5mm, so negligible difference. The FSA rings are ramped & pinned and shift as well as Campy Chorus IMO, so I can't imagine they wouldn't be the equal of DA in that regard. (not trying to start a Campy/Shimano flame war, just reporting my experience)
