I did a search on this but didn't find anything.
I want to convert my Dura Ace triple to an FSA compact. What does this entail? Can I use my current front deraillerur and front shifter, or do I need to replace one or the other, or both? Can I use my Dura Ace bottom bracket?
Thanks much.

Thanks much.The shifter will shift a double.The FD will probably work. The BB spindle is the wrong length for a double.

like he said...but some like to use a longer bb with the compact b/c they want to use the small ring on the higer gears....most likely a bad idea.

I'd stay with the DA triple myself and I run a compact.

Your current full-size crankset is a superior technology. Reducing the tooth count front and/or rear merely accelerates driveline wear and makes it harder to set up a good gear ratio progression. Compact drive systems are yet another useless fad, like indexed front shifters, which appears to have caught on.

with a 5 speed or even a 7 speed system I'd agree. But the fad is 9 or ten speed...easy to get progression. Friction is the way to go up front, but what are ya gonna do...copy some guy who won the TDF?
