    Strengths:    best buy for money.

    Weaknesses:    none i could think off.

    Bottom Line:   
    I am 95 kilogram . i have chainset mounted on hardtail bike that i use for freeride with a lott off drops and jumps. bein using it a lot for last two years. still in mint condition after lot off abuse . while asembling crankset have to pay attention on inner extractor bolt that have to be unscrewed and should not have spacers on for 73mm setup because it would not fit properly .

    Strengths:    Auto extracting crank bolt

    Weaknesses:    It starts creaking after about 5 rides and then the entire bottom bracket needs to be disassembled and buttered up. I'm not sure if it's the cranks or bottom bracket, or a combo of both, but I'm on my second bottom bracket and it creaks too. Everything is torqued properly. Everything else SRAM I've been impressed with, but I'm leaning towards XT for a new crank/bb.

    Bottom Line:   
    This may just be a mfg defect, or something SRAM has since fixed, but I'll never know because I won't ever buy another SRAM bb/crank, short of a no questions asked return policy.

    Strengths:    Strong, even getting rocks hits

    Weaknesses:    Didn't found any.

    Bottom Line:   
    I have used this cranks for all-mountain more than a year, and then passed them to the XC bike. I only ride weekends, and some XC races. They have supported drops (3-5 feet), rocks, everything that could hit them from below, and they never loosen or failed a shift. I highly recommend them, for this kind of usage. Best relationship in price/quality.

    Strengths:    It is cheap... And it does look good.

    Weaknesses:    It didn't even survive a ridiculous 1 meter drop... And no, i'm not riding a hardtail...

    I got some replacement parts but the whole thing was just beyond repair.

    The list of things that went kaputt is :

    - Main aluminium bolt which holds the left crank (The drop)
    - Groove on the left crank (gradually in the following months)

    Now the left crank keeps getting loose and has to be retightened every 15 minutes.


    Bottom Line:   
    Do. Not. Buy. This. Piece. Of. Junk.

    Strengths:    Great when installed properly.

    Weaknesses:    For some reason SRAM's instructions indicate a spacer is needed on the driveside of a 73mm bb shell. NO SPACER IS NEEDED.

    Bottom Line:   
    These have worked flawlessly for a couple of years now on my back-up bike (yes, it gets used a lot - especially in bad conditions). I'm wondering how many people below installed the 2.5mm spacer when using the GXP BB and Firex combo. If the spacer is installed on a standard 73mm bb shell, you will not be able to get the crank to seat properly, and all sorts of things will (of course) start going wrong.

    Strengths:    None

    Weaknesses:    Everything

    Bottom Line:   
    I weigh 170 pounds, I ride hard XC but no jump monkey. As I'm an engineer I know about installation torques blah blah. The most poorly engineered product I have ever had the misfortune to come across in 15 years of MTBing. Absolute garbage. Avoid. Zero chillis. My first experience of any SRAM product - never again by choice.

    Weaknesses:    design of bolt securing crank to spindle

    Bottom Line:   
    As others have reported, the bolt securing the left-side crank to the spindle
    repeatedly loosened; torquing it up to the recommended 55 Nm worked for
    a while, but then they began loosening again. When I couldn't keep them tight
    for the first 20 minutes of a ride, I had them replaced under warranty; we'll
    see if the replacement (the first set was OEM) lasts any longer.

    Strengths:    Works. Has lasted for ages without any problems.

    Weaknesses:    Not super-light, but pretty good for the price

    Bottom Line:   
    Works sweet. No problems at all, and i've done almost 6000km on the bike. Seems to be stiff enough for XC stuff.

    Weaknesses:    This is perhaps the worst Truvativ product on the market. These will fall apart if you use them for more than a month everyday.

    This product fell apart on a very busy Chicago street.

    Strengths:    Strong, great looks, fairly light weight.

    Weaknesses:    None so far. I didn't have to tighten the crank bolts once. I am 235 pound rider and haven't had any problems.

    Bottom Line:   
    This Shimano that came on my bike broke within six weeks. The Truvativ has been great for almost two years. I can't think of one complaint. I would recommend this to any rider over 200 pounds. For the money you can't beat it.

    Strengths:    looks.crank arms seem strong

    Weaknesses:    External GXP BB is absolute junk

    Bottom Line:   
    I had Race Face Evolve DH on my switch with external bb and thought it was the cats adss, which it was. When I got this bike, it had external as well which I really like from previous experience. I had the bike fopr just over three weeks and developed a nasty creaking. Took the pedals off, bb and the plastic sleeve that connects the two cups was buckled and cracked everywhere. It took me an hour to get the bb out of the shell, which should be a under 5 minute job.
    I am selling them on Ebay. 1 flammin turd for value, and 2 because they look good.

    Strengths:    they haven't snapped quite yet!
    although they sound like they are almost there.


    Weaknesses:    developed a severe clicking on their second long XC excursion, would not shut up despit repeated pull-downs and re-tightening. Hit them with loc-tite, just to have them still click and creak away despite being tightened to damnation. The mongrels won't settle down at all.

    Bottom Line:   
    Won't deal with any truvativ cranks again. Go the XT.
