Submitted by pamatte a Cross Country Rider from Eagan, MN

Date Reviewed: May 25, 2010

Strengths:    Carbon is strong. First year of the FSA crank was great. Once I hit 1000 miles, the squeaking started.

Weaknesses:    Squeak! Squeak! Squeak!

Bottom Line:   
FSA just does not cut it. They cannot get it right. Even with the washer that is supposed to fix it all. It did not work.
Time to get a lighter Shimano.

Date Reviewed: June 13, 2009

Strengths:    Easy to take apart... over.... and over......, and over again.
External bearings and uhhhh, you can attach a bash guard, but they weigh more than the large chain ring.


Weaknesses:    The thing weighs a ton and make a terrible squeaking/creaking noise when you pedal it and even when you pedal backwards. Apparently it isn't fixable or available for warranty claim. I tried everything, wasted hours searching the whole bike for the source of the annoying sound and came up with nothing but the same damn metallic squeaking noise from the crank/bottom bracket. 19 mm FSA BB1000 (bottom bracket) doesn't match any other crank spindles, this thing is an avoid at all costs piece of crap. FSA is hard to deal and won't back up their product. Had to replace small cog within one year because it was causing chain to stick.

Bottom Line:   
Never pay for this - do not accept it on your bike. Absolute crap. You can find more reliability anywhere.

Date Reviewed: May 28, 2008

Strengths:    Easy to disassemble

Weaknesses:    Weak bearings (Left bearing broke after 8 months)
Heavy


Bottom Line:   
I use my bike to and from work and occasionally take a trip in the forests of Trondheim. This crank came with my bike and has lasted less than a year of very mild abuse. I should have taken it back to the shop for a replacement, but decided I should rather upgrade to something decent. The 19mm spindle is not compatible with any other bearing on the market. I then had to choose if I wanted another (crap) Gamma Drive bearing, or if I should get a complete new crank-set. I just installed a brand new Deore XT set, which is 300g lighter. If the new Shimano crank is anything like the one on my former bike, I am sure it will :)

I can only recommend this product if you would actually like to go shopping for a new crank in the very near future (Who wouldn't? ;)

Submitted by Austin from Oregon

Date Reviewed: October 13, 2007

Strengths:    It hasn't failed yet. It is incredibly stiff and strong.

Weaknesses:    The bottom bracket tends to tear itself apart - starting with the little plastic cups that 'shield' from dust/dirt/etc. They're also incredibly heavy, however, a lot of that weight, as I found, lies in the chainrings. Rated for XC.

Bottom Line:   
If you get it on your bike at the shop, it's great for an entry level crankset. However, as an upgrade or replacement, I wouldn't buy another. It is immensely heavy for a XC crankset, but these other reviews don't do it justice, I feel. Also, having pulled off the small and large chainrings, it feels far lighter.

Submitted by Eric a Cross Country Rider from Oregon, USA

Date Reviewed: July 25, 2007

Strengths:    Looks nice, external bearing bottom bracket.

Weaknesses:    Are designed so that a pedal wrench is a requirement to install pedals, if one is not used it will feel as if the pedals are tight when they are not. Middle crank ring also won't fit shimano cranksets with out some grinding.

Bottom Line:   
Seemed like a good crank when I got it, but the pedals mounts got fubar'd because of the weakness mentioned above. I've known more than just me that have had this problem.

If it comes on a bike that is assembled from a shop, check before you leave, but I wouldn't buy them aftermarket.

Date Reviewed: July 3, 2006

Strengths:    Bends like blades of grass. (I'm 140lbs)

Weaknesses:    BB still holding up.

Bottom Line:   
Bent them twice. First the left side, on a small drop. I never crashed when it bent. Figured it was a fluke. Got a replacement. Month later I bent the drive side into the frame hopping a 6" log. Never crashed. These are the worst cranks I have ever used. I guess they'd be okay if you were 70 pounds and never so much as went over a curb.

Submitted by James Jordan a Weekend Warrior from Bonita Springs

Date Reviewed: March 9, 2006

Strengths:    cost; and can take a beating with the trails and with the torque wrench

Weaknesses:    in reality, none.

Bottom Line:   
You will not beat these cranks for the money if they are on your bike from the shop. Get yer legs, then sort out the upgrades. You CAN torque the pinchbolts on the L arm to keep it from creaking; lithium grease all the loaded points and they will last; 19mm spindle has it's drawbacks, but c'mon,... whast you see is what you get.

Strengths:    STIFF CRANKARMS, EASY REMOVAL, STRAIGHT SPIDER AND RINGS.

Weaknesses:    CRANKARM REMOVAL A LITTLE TOO EASY IF PINCH BOLTS ON NON DRIVE AREN'T TORQUED DOWN BIGTIME. HEAVY AS @#%&*. DRIVE SIDE BEARING LOOSENED UP AFTER 20 MILES, NEVER HAD SHIMANO DO THAT IN 15 YEARS!!!

Bottom Line:   
NOT CHEAP ENOUGH TO JUSTIFY HIGH MAINTENANCE THUS FAR. THE COMPETITORS: SUGINO, SHIMANO, AND TRUVATIV HAVE BETTER FOR LESS $$$$ THE HIGH END FSA STUFF LOOKS BULLETPROOF N LIGHT(DIFFERENT MATERIALS AND LAYOUT). BEST OF LUCK. ASK THE SHOP TO SWAP IT. WHO SHOULD BUY IT? DARNED IF I KNOW. WHO SHOULD STAY AWAY? DIRT JUMPERS, HUCKING DOWNHILL, SLALOM ETC. ANYBODY WHO LIKES HAVING FUN ON 2 WHEELS FOR THAT MATTER.
