Strengths:    Look good, strong, do the job without issue.

Weaknesses:    HEAVY, pricey is bought aftermarket.

Bottom Line:   
To me these are just average cranks because they don't do anything beyond that. There is no reason to be a 100 grams heavier than Shimano. Thats bad design. If they are hollow, they sure must barely be because they weigh so much. I don't know how they shift with stock rings because I went Wickswerks immediately because I wanted near instant shifting which they deliver. Think about it...big ring has 11 shift gates vs. 2! No more waiting for the pins to make the shift or waiting for the chain to drop to the next ring, awesome. Personally, this whole hollow forged thing is a pointless gimmick and believe you can get equal stiffness and weight savings by simply using an I beam design like raceFace.
Bottom line is yes they work great and look great but theres no reason for a quarter pound weight penalty , thats inexcusable.

Strengths:    Solid, fairly light, smooth

Weaknesses:    None yet

Bottom Line:   
Good cranks, nothing special. Could be lighter, but good overall for what they are and the price. No chainsuck issues at all. I have the 2011 Dynasys version (24/32/42). The design makes it a little harder to clean the teeth on the non-big rings than others but no big deal really.

Strengths:    Durable. No shifting issues. No play in crank when properly (re)installed. Good availability of overhaul parts from FSA.

Weaknesses:    Granny ring wore out after a year and a half, causing major chain suck in damp conditions - what do you expect from aluminum? Crank arms scuff easily.

Bottom Line:   
Get a steel granny ring when the original wears out, don't look at the crank arms too closely, and ride the Afterburner into the sunset.

Strengths:    shifts fine
neat looking chainrings
crank has never given me any problems


Weaknesses:    heavy
expensive
scuffs easily


Bottom Line:   
overall, these are decent cranks, but i probably would've gotten something else if i had to do it over. the cranks i got weighed in at 980 grams, which makes them heavier than shimano lx. together with the high price tag (almost as much as shimano xt), you could do better.

also, you need to periodically check the crank arm, as it has a tendency to come loose over time.

Date Reviewed: September 26, 2008

Strengths:    Ease of installation (though frame bb shell had been machined), stiffness, smooth bearings, now have decent allen key chainring bolts (instead of torx), value at price paid

Weaknesses:    A little heavier than some competitors and 100 gms more than taper set up (FSA Ultimax titanium) but really none so far, but the overall design of external bearings makes chainline adjustment very restricted

Bottom Line:   
Strong, smooth and easy to install. If bearings last then I will be happy with this set up. Nearly did not buy FSA as previous Ultimax Ti BB bearing failed prematurely and they are NOT user replaceable.

Strengths:    Looks cool, Fairly Light, Strong, Durable, Precise, could be used for some FRing

Weaknesses:    Color wears off quickly.

Bottom Line:   
I bought this crankset as an upgrade to Shimano Alivio. What can I say? The difference between the two is like day and night. FSA Afterburner Megaexo does what its meant to do, without a question. Cranks stay tight, bearings dont make any sound. I'm doing 4 feet to flat with these, they look strong so far. I'm 170 lbs and I'll be using them for some freeriding this summer.

Aside from those, color on crankarms wears off quickly. Because it looked kinda bad, I removed all the color with a color remover :) Now they look super sexy (the outer chainring desing and color adds to this sexyness).

Great product.

Date Reviewed: March 13, 2007

Strengths:    Very smooth shifting, not too heavy, not much flex, splined so not as prone to creaking as tapered. Looks OK too.

Weaknesses:    The black finish wears off easily.

Bottom Line:   
Fitted after the supplied square taper BB and Shimano M440 cranks finally gave up, the Afterburner made a huge difference in performance. Shifting is much more immediate and far smoother. They are also noticeably stiffer than then old Shimano cranks (but then they are 4 times the price).

The black finish on the crank arms quickly wore off where my shoes rub so it looks a bit scruffy but the chainrings themselves remain neat and still have all their teeth despite some close encounters with logs etc. They aren't showing any significant signs of wear yet either and shifting performance remains good.

The supplied Mega-Exo bottom bracket was easy enough to install but be careful not to over-tighten or the spacers could easily buckle.

Use of a pressure washer has been careful for fear of forcing muck through the seals but they've been through a dusty summer and muddy winter, totalling 700 - 800 miles, and survived without problem (so far).

For the price, I am more than happy with them, and they're even cheaper now than when I bought them making them better value.

Submitted by Richard a Cross Country Rider from Canada

Date Reviewed: July 22, 2006

Strengths:    Very strong, durable. By moving the bearing to the outside of the frame it has taken the flex out of bottom bracket. They shift extremly smooth. The come with aluminum chainring bolts to reduce weight. but why are they torx?

Weaknesses:    None so far.

Bottom Line:   
This is an exellent crankset for the money. When you install these make sure you leave a very small gap between the left crank arm and the bearing spacer. If you try to make it snug you will place too much preasure on the bearings and they will make a snaping sound. By backing off the left arm they run perfectly quiet and will perform great. They also include washers that go between the crank arm and the pedals. This will stop the pedals from cutting into the aluminum crank arms. This crankset is intended for XC riding and not freeride or downhill.

Stripped FSA Afterburner Megaexo crank bolt

Hey somehow I managed to strip the hex slot on the left side crank bolt on my FSA Afterburner crankset. Any idea where I could get a new one? A google search gives me plenty of results, but they all say they're good for FSA's carbon cranksets, not their afterburner set. Thanks!Read More »
