FSA compact crankset question

[jj1075]

I was wanting to go from an Ultegra triple to an FSA carbon compact double.
Will I need to switch front or rear derailleurs? Or anything else for that
matter?


Thanks in advance,

Jeff Jackson

Nothing needed to change excpet the BB(109.5 if octalink, 108mm if ISIS used)
and perhaps chain length. The FSA will work fine with both ders, even if the
triple version.

I think your Ultegra Triple front derailleur will work but a DA 7700
double will work better.

You'll also need to lower your front derailer by about 2mm for each
tooth decrement - i.e. if you go from 52T to 50T, lower the front
derailer by about 4mm.

Thanks for the answers and fine advice, all. I'm gonna do it.

Also, if you go with the Platinum Pro Ti or Platinum Pro bottom
bracket, the cups are a "structural" part of the bottom bracket,
meaning that they snug against the bearings cartridges and hold
them tight against the center sleeve. You need to grease the
rubber seal on the inside of the cups so that they slip over the
bearing cartridges and hold them in place. If they do not seat
properly, you will get some rocking, like the BB is loose. It is
a somewhat odd design in my book. -- Jay Beattie.

I'm interested in hearing your results after swapping the crank.
If you are going to also switch the derailleurs, It would be interesting
to do that last and try the Ultegra triple, then the D/A to compare the
difference.

I'd have thought a triple would handle a 30/50 chainring better since
that's a big 20 tooth swing.

Also interested in how the STI lever shifts the compact.

Good luck

I'll let you know via a posting in this group in a few weeks. I am going to
keep the triple derailleurs. I'd like to keep the rupture in my wallet down
to a minimum.
