anyone have the FSA carbon pro compact crankset?
how is it? quality, shifting reliability, gear range, availability of replacement chainrings, etc.
in short, how about a review.

in short, how about a review. Chainrings are 110BCD.Nothing new there.
The new VeloNews profiles five or six new cranksets, including a carbon model from FSA. I don't remember if it's the compact pro model or not.
FYI, for whatever stock you put in their testing, the new Dura Ace alloy crankset was the clear winner in terms of stiffness versus weight, at a moderate price. Also tested: the $900 Colnago carbon crank, the new Record carbon, a new carbon Profile Design and TruVativ's latest Rouler alloy.
I just put the 175 mm FSA compact in Octalink (34/50) on my newly built-up Carl Strong bike (Foco steel with Columbus Super Muscle carbon fork and stays). I decided to mix 'n match on this bike: 7700 (pre-2004) Dura-Ace (109.5 mm) BB; brakes are 7800 (2004) Dura-Ace; all other components are Campy Record (pre-2004). Cluster is 12/25.
So far the crank seems very good. This weekend I did some climbs that were 8 to 10% grades. My son was riding with a Campy triple (30-40-53) and both of us had no problems.
The FSA crank is light and with my rear cluster covers a really great range. I noticed no flex, manifested as movement or chain rub, when riding out of the saddle. I do get flex with the 7700 Dura-Ace 39-53 double using the same BB (my weigh is 78 kg). I also get flex with the Campy Record triple when out of the saddle. I therefore find the FSA compact carbon crank to be very stiff.
Nor do I get flex with Graeme Murray's adjustable carbon crank using the same BB. In fact, you can run his crank as either a double or triple with the light 109.5 mm Dura-Ace BB. (Refer to http://www.murraytourdeforce.co.za/index.html for more details.)
BTW, the Pinarello carbon crank is the same crank as the FSA compact carbon, made for them by FSA (or actually, as I understand it, the company in Italy that makes the crank for FSA.)

thanks, robert. this is the kind of info I wanted...from owners/users.
I have been using this crankset on my Specialized E5 bike for about 2500 miles this summer. I love it. Pairing the 34/50 chainrings with a 11/23 cassette actually gives you a greater range of gears than a standard 12/25 39/53 setup. I love the easier gear on climbs and the longer gear on the decents. The tradeoff is a bit greater spacing between gears. I occasionally run this crank with a 12/23 casette which ameliorates that. You could even go to a 12/21 for that matters. Siffness is great, looks are even better. Costs about $250-300 dependning on where you buy it and saves a good 100g. You also save quite a bit of weight (about 30-40g) shortening the chain. I use a SRAM R89-hollowpin chain that weighs only 248g after I shortened it for the compact crankset. Hope this is useful fro someone...
Just a question to all those that have this crankset - Were there problems getting replacement chainrings of these sizes (50/34)?? Thanks!
Good question. I haven't had to deal with replacements yet. That said, FSA has an excellent customer support. I would be surprised if they didn't have an answer for that.

The crank has not been out that long and I've never worn out teeth on a crank that fast, so I haven't checked for replacements. Since it uses 110 bcd rings, I don't think it will be a problem finding parts; this is a common size for MB and Tourers.
Now if you're asking can you replace the rings with different ratios, well that would depend on your FD, RD, and rear cluster.
Most RD handle about 14-16 teeth on a front ring, and that's what the 34/50 gives. The 34 won't go lower because of the 110 bcd. On the other hand, you might increase the large ring to 52. There's a firm in the UK that will for a price custom make just about any ring you might want if you can't get it from FSA: Highpath Engineering ( http://www.argonet.co.uk/highpath/cycle.htm ).
Check out ActionTech. They make Titanium chainrings for 110mm. They range from 34 to 56. They are not cheap but appear very well made and should fit.

Question for everyone again - I have a double crank shimano ultegra (53/39) and would like to replace this with the 50/34 CR from actiontec specified by HarryS, I wasnt able to measure the BCD right now but will the 110mm CR fit the ultegra crankset??? Thanks again!
"Normal" Shimano cranks have a 130 BCD. The smallest chainring you can get for those is a 38.
Does anyone know of any cheaper high-quality alternatives for a 110 BCD crank? I've heard that FSA is making/is going to make a non-carbon version of the compact crank, but haven't seen anything more than a one-off mention of it on a news site.
No, they are not. They are 130mm BCD. You should be able to find different chainrings for that crank as well. I don't belive a 34 is possible with that crank but a 50 should be. FSA makes some from 38, 39, 42, 44, 46, 48, 50, 52, 53, 54 and 55 teeth. You can see their webpage at

Thanks! That's what I thought too...
email from fsa said they have replacement chainrings in 110 bcd in the following sizes: 34, 36, 38, 48, 50, 52
TA makes 110 bcd, such as the Zephyr.
Take a look at Peter White's site: http://www.peterwhitecycles.com/zephyr.asp
While the Zephyr is no longer made, Peter has stock and many replacement rings. Also, TA makes a newer model that replaced the Zephyr.
For my FSA Pro_team carbon the 38 ring sounds interesting...
Teff
Teff,
The Pro Team isn't 110 is it? I thought it was a 130, for which the smallest ring is 39.
