Strengths:    Looks , Weight , Bottom Bracket

Weaknesses:    Warranty

Bottom Line:   
Used it for as Year , right arm came loose , changed bolt, washer . Came loose again , sent for warrant , and received a regular FSA K Force , not tTitanium for which I paid an additional 300 dollars. No answer from FSA , no apology , and NO RETURN of my Titanium Set for which I could have purchased a right Arm .
Try a different product from a reputable Brand . This is not one of them.
You must stand by what you sell and FSA does NOT.

Submitted by D13 a Cross Country Rider from Palmdale, CA USA

Date Reviewed: September 15, 2009

Strengths:    Light, look great, feel Great

Weaknesses:    Carbon can chip very easily on the bottom of the crank arms! I've had these for less than three months and they may not last me as long as I would have hoped for. Very expensive to potentially replace them.

Bottom Line:   
I paid a lot of money for these cranks but now i'm wondering if carbon fiber is worth the price. I could have hit the same stuff with XTR and would have looked at dents and scratches. Now i'm looking at a big chip and broken chips on my left crank arm. Really sucks!

Date Reviewed: March 21, 2009

Strengths:    Light crank arms can take a serious beating

Weaknesses:    Ceramic BB is crap. Massive amounts of play after 6 months of riding. The wave washer cracked and probably caused a good part of the damage to the BB. Don't install the cap for the self extracting bolt it will fall off, just keep it in your toolbox for when you need it.

Bottom Line:   
This was a warranty crank for a Team Issue Carbon crank that had the pedal inserts fail. The BB is a very expensive weak link to this otherwise well built crank. No other BB's that I am aware of will work with this crank so until they improve the BB I would absolutely avoid this crank.

Date Reviewed: March 8, 2009

Strengths:    Beautifull & stiff. The carbon is vulrenable, but does the trick. Shifting without any problems.

Weaknesses:    No MegaExo self-extracting cap pin tool!!!! and they are way expensive.

Bottom Line:   
They are beautifull cranks. Very stiff. A bit fragile, but the scuffing is not really noticable, nothing to be worried about. BUT, the selfextracting crankbolt needs a special tool, which you don't get! You'll be able to install the cranks, but won't get the bolt, as secure as you want to. The tool will set you back at least 20~30 bucks. For such an expensive product, I hate these surprises.

Submitted by Goliath_2 a Racer from Washington state

Date Reviewed: November 16, 2008

Strengths:    Extremely light, stiff, great shifting, SUPER smooth bearings...and they look Spectacular!

Weaknesses:    High Price (?) Also, bearings require more frequent maintenance.

Bottom Line:   
Beautiful cranks. They're extremely light and surprisingly stiff. Haven't had any issues and the BB is running very smooth. Apparently the ceramic bearings require more maintenance (regular cleaning, greasing) but that isn't a big deal for me as I'm typically pretty on top of that sorta stuff anyway. Somewhat pricey but they're a flagship, elite level, cross country racing crank from a company with a reputation for making great stuff.

Submitted by pedalitup a Cross Country Rider from Oregon

Date Reviewed: September 14, 2008

Strengths:    This review is for the 44/29 version.
Its beautiful, 740gms with BB-9000 (steel) bottom bracket.
It's super stiff under pressure. The shifting is absolutely flawless compared to previous attempts at 44/29 setups I have tested. The chainline is wider than stated which eliminates the possibility of the chain rubbing the big ring when using the smaller outer cogs with the 29t inner ring. After actually riding it, I must admit this is brilliant. Get an 11-34 cassette and the ramps on a shimano front derailleur seem to match perfectly so theres no rub there either. If you're not strong enough to climb what you need to with a 29/34 gear you probably need to stick to the 3 ring version.


Weaknesses:    The online pdf instructions differ from the parts I got with the crank. The Q factor is designed for a 73mm BB shell so the pedal stance feels really wide. The inside of the crank arms are 12mm from my chainstays! My XT front derailleur is very close to the outer limit of its available range compared to every crank and BB I've tried on this frame. The chainline is designed for really strong "elite level" racers as stated in the catalog. Not really a weakness, but worth a mention here.

Bottom Line:   
I just hammered this work of art for the first time and did a personal best of 2:55 on my 40 mile loop. 13 minutes off my previous best time. I've ridden this loop dozens of times and changed nothing else on the bike but this crank and the cassette to 11-34. What more do I need to say ?
Ive never purchased an FSA product I didn't like.
I wish they would come up with a completely dialed XC racing driveline and shifters like SRAM did with the red road group. I give it 5 flamers having only paid $250 for it. I give it 4 overall only because of the long spindle.

Submitted by chcmuzza a Weekend Warrior from Christchurch, New Zealand

Date Reviewed: June 24, 2008

Strengths:    Light, strong cranks, which have taken a hammering without breaking.

Weaknesses:    The bottom bracket. The ceramic bearings have less than 1200 miles on them and the non-drive side has seized. They have been wet occasionally however there are no instructions on FSA's website on repacking the bearings so it is not obvious what level of maintenance is required. Given FSA suggest longer life with ceramic one could assume less maintenance than steel.


Bottom Line:   
The cranks themselves, great. Given you can't buy the cranks without the ceramic bearings (which was the reason I purchased this crankset in the first place) then potentially a waste of money. Will replace the BB with the steel version at 1/3 the price.

Submitted by Jesse a Weekend Warrior from Drexel Hill, PA USA

Date Reviewed: July 5, 2007

Strengths:    This is FSA's newest MTB and road carbon fiber crankset and it blows every other carbon unit on the market away!! I have a genuine Race Face Next LP on another bike and the K-Force Light is actually stiffer and lighter than my Race Face!!!! The included ceramic bottom bracket is VERY easy to service and requires much less maintenance than regular BB's.

Weaknesses:    NONE!!!!

Bottom Line:   
BUY THIS!!!!! You will not regret it!!!
