Strengths:    Performs to my expectations on sprinting and hill climbing, absolutely no DR rub.
Good looking, hard glossy carbon finish prevents shoe rub marks.


Weaknesses:    None

Bottom Line:   
Over 6000+ miles, Bottom bracket standard mega exo still smooth, very stiff with absolutely no movement when hammering (6' 170).
Worthwhile tweek is to change to FSA Super Chain rings, worlds stiffer from standard.
A real Bargain Crankset

Strengths:    It's cool looking.

Weaknesses:    Everything comes loose. Within miles. And with loctite.

Bottom Line:   
This thing sucks donkey balls. If the left crank isn't coming loose, the outboard bearings are.

Also, with Campy Record 10s the chain drops between two chain rings and doesn't engage the small ring. It has to be thrown over to get it work.

Strengths:    ?

Weaknesses:    chain slip with downshifting - basically if you cannot downshift safely the product is worthless

Bottom Line:   
The FSA-SL Carbon crankset came on my new Cervelos RS (2008). I also had problems with the chain dropping from the large to small crank such that the chain would slip. It is amazing to me how any crankset could be built this terribly these days. I brought it back to the LBS and they swapped out the chainrings for ultegra and it works well now.

Date Reviewed: July 7, 2008

Strengths:    Looks nice.

Weaknesses:    Too much flex. Poor chainring design.

Bottom Line:   
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:    none

Weaknesses:    crap carbon. No more carbon for me. Ti it will be from here on in.

Bottom Line:   
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!
