Rated 3 out of 5 by Anonymous I've had these for 5 years, they've served me well doing occasional street/jumping/trials and lots of trail riding. They are definitely up to the task and can be ridden hard, but now the bearings are finally gone. They have developed a lot of lateral and radial play as I found when the entire crank assembly wiggled a lot even when done up tightly. This might be due to my slightly trial-and-error installation, but I blame the fact that there are no instructions - FSA could really do with including these, I'm sure they wouldn't cost much to print but would really help the customer! Also, the spacers which look like crud seals are in fact pointless so I just used them further out on my axle. The bearing seals are cr** which didn't help either.
Oh yeah, and they weigh just under 2 kg
If you're looking for a tough set of cranks that you're not going to get too dirty, and you know how to install them already, get these

Rated 5 out of 5 by Anonymous Awsome cranks been running these for about 2 years. I ride DH and have had no problams at all ive got the shorter ones though as they give more clearance round corners e.t.c but that is really personal preference <br>little bit expensive but an awsome cranks

Rated 3 out of 5 by Anonymous Theyre alrite but no instructions which is a really bad thing I screwed mine up when fitting them. they work alrite now though, but not sure about durability cos i haven't ridden them hard yet. they look quite strong but not as strong as dmrs or some other beefy cranks

Rated 5 out of 5 by Anonymous These cranks will not be subject to bending or breaking they are quite invincible, can be used for all types of riding.

Rated 3 out of 5 by Anonymous They're OK if you like puzzles and problem solving. A real bitch to set up, no instructions you see... I had to try 3-4 times to get them work. Otherwise pertty good cranks, seem to be solid and durable. Quite lightweight compared to the DMR Chieftains... And ugly as hell ;) If you have the extra money, buy the chieftains, but if you're short on budget, get the FSA set

Rated 4 out of 5 by Anonymous These cranks are well worth the price.<br>I havnt gone that big yet but hey really feel solid<br>a bit on the heavy side though (about 3kg)<br>the biggest minus is the loss of instructions, you have to figure out how to install them yourself but otherwise they're a pair of ace cranks

These use an FSA X Drive bottom bracket which comes supplied with the crankset. This is not compatible with ISIS or Square taper bottom brackets so you would need to use the bottom bracket which has been supplied.
The X Drive bottom brackets are similar to a BMX bottom bracket.
