change FSA Gossamer compact for Shimano R700 compact crankset

JensonUSA has the R700 cranksets for $95. I currently have an FSA Gossamer compact and I'm wondering whether this would be worth the upgrade/swap out. I'm not unhappy with the FSA, but not exactly thrilled with it either.

does anyone ride this crankset? What are your opinions?

If you have a lot of miles or cosmetic damage to the FSA, then the change makes sense.
New CW and spiffy looking blinged up cranks, nothing to lose. Jensen wants you to do it,
so it makes even more sense. Price is much better than average for the Shimano.
Functionally there will be little difference, Chevy vs Ford, presuming you have MegaExo
version of the Gossamer. If the pre MegaExo version then you will need the external
bearings, probably sold separately with the Shimano.

The Gossamer is about the crappiest crank you can ever buy. Hell I had a $30 shimano steel triple that shifted better than it. That being said if the OP is happy with the shift performance (I wouldn't) then don't spend any money. If he isn't, the R700 will be about 99999x better upgrade. The only reason why that crank is spec'ed on OEM bikes is for price-point reason. It is probably one of the worst shifting crankset I have ever seen - especially on Cervelos

Haven't noticed any shift problems with the Gossamer pre Exo compact I used for
several years, maybe because I used Centaur brifters and an FSA FD(?)
Our tandem also had FSA Mega EXO Gossamer triple and it was not so fine in the shifting,
OTOH replacing it with FSA carbon triple didn't really improve matters much.
Not too many options with tandem cranks though. Gossamer is low end but not
POS in my experience. A good bit of the shifting problem on the tandem lies with
the pilot however (high torque shifting, unannounced).

For the record, i'm talking about the mega exo, fsa gossamer compact 50-34.

It's not the FSA cranks that are the problem, it is the chainrings that make the shifting not so great. Replace the chainrings with something better and you'll be fine (Shimano rings shift the best, TA give the widest size options and shift decently). Unfortunately, you can often get discounted cranksets for less than you can get the same set of chainrings separately (I don't mean that it's unfortunate that you can get cheap cranksets, I mean that it is unfortunate that chainrings are relatively expensive). All in all, the Shimano R700 has far superior cranks and rings than the FSA Gossamer.

I find it incredible how many mid-level road bikes come stock with the FSA Gossamer crankset - they must be virtually giving those things away to the bike builders. If you find a new bike that has a stock Shimano crankset then you can be pretty sure that the builder has not been scrimping on the costs anywhere.

That crank is stock on most Specialized Allez of recent years, if it is the compact version of the bike. I just removed one from a 2009 sport version. Nothing wrong with it (except it was a compact crank - not my cup of tea).

I would have, but it is already gone. Sorry about that. Someone at the LBS wanted it for a conversion going the other way. $25

BTW, here is exactly what you want, with the BB, brand new, for $68:

After I typed it in I realized you had asked about the R700 Crank, not the R600. The R700 is the ultegra version if I am not mistaken. I sold an R600 with 3000 miles on it, which is what Specialized puts on their Allez models.

I'm going to buy the Shimano from JensonUSA. i already have a DA7900 BB. I'll move the FSA to my gravel road bike.

In my opinion, that is a good thing to do. My own experience with the FSA Gossamer compact (on my daughter's bike) is that it never shifted all that well and she had difficulty. I installed a 105 compact crankset and the problems she had simply vanished. The R700 is a step up from that, so you're likely getting a lighter and stiffer crankset. All to the good.
