Description This version uses 130mm BCD 53/39 chainrings. The MegaExo oversize cartridge bearings are housed in alloy cups, and the BB spindle itself is made from super-tough CroMoly steel.
Summary: Had it on a Litespeed Tuscany and then a Cervelo R3. Had a lot of flex in the crankset and chainring, causing my chain to rub on my front derailleur - no matter how many times I adjusted it.
The chain would occasionally land on the chainring teeth, causing it to slip and then catch - UNSAFE.
Moved to FSA Carbon Pro Team Issue (octalink) and it's like night and day.
Strengths: Looks nice.
Weaknesses: Too much flex. Poor chainring design.

Summary: Piece of crap! I've only had this crank on my new bike for about 8 months (about 5,000km).
The damn thing cracked from the pedal upwards!
No notice. Just got on the bike and notice the pedal was a bit loose. Look down and there is this massive crack!
Strengths: none
Weaknesses: crap carbon. No more carbon for me. Ti it will be from here on in.

Summary: I have had these cranks for about 3 years. Due to the number of miles I put on each year, I have been replacing them every year (luckily under warranty each time). I have broken these cranks yearly. With the amount of money being spent, you would expect a longer lifespan than what I was getting. I have had the metal sleeve for the pedal spindle crack on me a couple of times and I have had the carbon crack on me. If you are looking at this product don't buy it, either go more expensive and stay with carbon cranks or get aluminum cranks.
Strengths: Cheap carbon cranks but you get what you pay .
Weaknesses: Need Locktite to keep crank on. Short life span.

Bike Setup: '05 Cannondale R1000 CAD8, FSA k force carbon stem, FSA k wing bars, Shimano Ultegra shifters, derailuers, Mavic 2007 Elite wheelset, Conti GP 4000 tires, Fizik Airone saddle, Easton Carbon seatpost, Durace pedals, Shimano Flite deck.
Summary: I was worried about the cranks coming lose via all the reviews but got a great price on it brand new. So I gave them a try...Now I have over 6,000 miles on them and they are still tight, no creaks and I have be over-all very happy with them.
Strengths: Look great, carbon dampens the road vibration, and stiff. can change to compact chain rings. Matches my stem & bars.
No chain suck....flawless.
Weaknesses: none so far.

Summary: Well, it seems as though any problems these cranks had have been fixed. Been doing a lot of riding, and so far not a single problem. Cranks are still on tight and no clicks, creaks, or squeaks at all. It was actually very tough to get them on they were so tight. I have no concerns about them coming loose like others have written about. These things work great, shift great, and look great.
Strengths: Stiff, look really sweet.
Weaknesses: So far none.
