Strengths:    Light, stiff, good looks, superb chainrings - they last a lifetime!

Weaknesses:    Left arm was coming loose after like 50hrs of riding. It turned out to be manufacturing problem. FSA gave me finest quality service and replaced the whole set. I was shipped a brand new, boxed SLK cranks, installed them and they have all the previous had, plus left arm never came loose.

Bottom Line:   
Mixed feelings but with great final. Came stock with the bike. A great product. Since replacement no problems whatsoever.

Strengths:    uh?

Weaknesses:    See above. Who wants to change BB every month? Customer service has been challenging to work with.

Bottom Line:   
Absolute worst crankset/BB I have used in 25+ years of racing & training. The BB come brand new with an ugly grinding sound - produced while spinning the crank without any load. Sure enough, the bearings seized within 1,500 miles. Thus, 2 BB sets within 3 months. This occurred in dry California conditions.
Front shifting lacked the crispness that comes with a Shimano or Campy crank.
What's worse, the design of the securing mechanism leads to failure. Non-drive crank loosens, and finally, when reinstalling crank for 3rd BB, non-drive crank stripped while applying spec load (measured w/Park torque wrench). Now sawing crank off to replace w/Dura Ace. Bottom line- AVOID!

Strengths:    Modern tight carbon weave with a great power transfer.

Weaknesses:    Slightly heavier than Team Issue with ISIS Ti BB.

Bottom Line:   
This is a strong percise engineered stiff carbon crank. The item is straight and shifts quite well, with a nice modern strong carbon weave. The bearings are smooth the power transfer is great with a bit of a spring. This really is a great crank.

Strengths:    -price, price, price!
-performance-to-price ratio
-looks cool (matches this particular bike well)


Weaknesses:    -a tad heavier than many others out there but for this price...
-FSA bolts are really soft; easy to strip the threading
-Noticably noisier than the big brands
-Make sure to use proper torque wrenches and follow always FSA's recm'd specs (any FSA bolts are really easy to snap/strip)


Bottom Line:   
I don't know what everyone is complaining about, but maybe I'm just lucky, like with every other badly-rated components I've bought. I would attribute it to the installation process, even if it was done "professionally." I've purchased a lot of FSA products - cranks/BB's/seatposts/Plasma handlebars (I actually live in the city of their world headquarters - Taipei!) and every single one has had its bolts stripped from just ever-so slightly over-tightening. All for the sake of saving a few grams of weight!?!?! Good thing that my trusty LBS never really tightens anything. Never came across this problem with any other brand where durability overweighs the sacrifices in weight. Weight-weenies don't actually ride/race their bikes I'm sure-wouldn't risk things snapping I'm sure!

In all fairness, I've used this crank - my 3rd SL-K (but first Mega-EXO) over two years and several thousand kms without any problems at all. I've bought 3 different FSA carbon cranks already and they're all fine. The crankarms themselves are fine, just not their FSA (ISIS) BB's. I chose this crank to replace another problematic SL-K (non-Mega-EXO) with a FSA Ti ISIS BB that was on this bike initially. I had replaced that pricy P.O.S. BB 3 times in 2 years! They kept developing a really annoying and noisy creaking/clicking sound after only ~1000 km. It was the same on 3 different bikes. Couldn't nail the problem for the longest time like exactly which part/bolt/washer/bearing was causing it. After that, I had enough and swapped to the then-new Mega-EXO and voila! Never any annoying sounds again. The crankarms themselves though are strong enough for me, but I'm only about Lance's weight - and I do thrash them and they've held up well.

Mine actually came with the better (?) K-Force chainrings but hands-down, the teeth-profiling is still not incomparable even to the mid to low-end from Shimano/Campy in terms of smoothness/shifting. They're definitely noisy in comparison. The BB is certainly not nearly as smooth as the the better brands, but like everything else, you get what you pay for!

SLK MegaExo Bearing Question.

I have a very annoying creak coming from my bottom bracket. I took the cranks off and noticed the drive side bearing was stuck to the crank and not pressed into the cup any longer. I pressed it back into the cup (went in easy - too easy). Test ride around the block, creak was gone. First real ri ... Read More »

FSA Cranks- Pro Carbon Isis or SLK MegaExo?

My wife's new bike came in with an FSA SLK Mega-Exo crankset (like Shimano one-piece system). We wanted compact 50/34, but the SLK was 53/39. So the shop put in a Pro Carbon 50/34 with an Isis bottom bracket. Did we get ripped on that? Anyone know the real differences/weights/virtues of the ... Read More »
