    Best Lightweight Crank?

    Im thinking of finally getting a proper lightweight Crankset to shave some Grams. Im now running the Truvativ Stylo Oct 3.3 converted to a 2x10 with lightweight Bash guard.

    The listed weight on the Stylo Oct are 845g with GPX BB mine is probably close to 800grams without the large chainring and light Bash.

    What are the Top lightweight Cranks in the $300-400 range. The XX has good reviews but is 754g and the XTR's are even heavier...

    Are there any cranks in the 650-700gram range that are still strong and reliable or should I just stick with the Stylo Oct?

    Ive heard Good things about the Noir. The SRAM website only lists a difference of 45grams between the Noir and Stylo Oct... Thats not nearly enough for me to make a switch

    Nice! Do you notice any flex with it? Also, where can the s-work cranks be purchased online?

    I don't notice any flex - super stiff as there is no weight limit on these cranks.I'm 150 lbs.
    These are the stock cranks on every S-Works bike sold.
    To purchase:
    Specialized.com
    lightningbike.com
    Extralite chainrings = fairwheelbikes.com
    bbgbashguard.com
    Note: The Lightning spider & lockring is 22 grams lighter than the Specialized spider/lock ring.
    The Lightning lock ring tool was $20.00.

    Ace, S-Works cranks don't work on every BB. eg. 92 PF, 73mm threaded.
    I rigged these up to work on a 68mm threaded BB with Hive cups.

    Hollowgram SL

    These are amongst the lightest,stiffest and sexiest cranks on the market however it will set you a little more than your budget.

    yes they are extremely stiff

    Yeah, I forgot there was a reason I wasn't looking at these as an option... What did you BB setup end up weighing?

    Get the new Race Face Next SL 2x10 crankset. It's light (610g including BB) and compatible with every bottom bracket standard (*), and costs half as much as the Hollowgram SL. I haven't tried it yet, but my Next SL triple is also very stiff and shifts as well as the XTR crankset it replaced.

    (*)
    BSA -> Race Face Turbine X-Type (included with the crankset)
    Press-Fit BB92 -> Race Face ∅41mm Press-Fit (BB92) → X-Type (sold separately)
    BB30 -> Race Face BB30 → X-Type Adapter (sold separately)
    Press-Fit BB30 -> RESET PF24

    Double dong on the Noir. Light and stiff.

    Go with a colored one if that's your game.

    I wwill be hunting for Noir myself, occasionally a 3.3 set without BB will show up new on fleabay for about $210, thats almost as low as what a Stylo OCT with BB cost. I'd like the Noir but can't afford to spend $100 premium for it over the Stylo for only 50 grams of what so when the time comes I may end up with another Stylo OCT, I'll be looking for $150 deals online soon.

    xc71,

    Are the specialized crankset the same as the lighting crankset? If so can you not just run the lighting bottom bracket cups? Especially for standard 68mm threaded bottom bracket frames...

    The Lightning are the same with the exception of the axle.Lightning offers different length axles for diff. BB. The S-Works axle is only 90.7mm.

    RF Next SL.....Hollowgram....all way beyond his budget.
    I don't think there is really anything light in that budget.
    Used XTR,XX, maybe Aerozine and KCNC....
    Maybe some older FSA Carbon cranks, run them double with a Omni Racer BB.

    All others are $500 and up....THM Clavicula, Storck Powerarms, Lightning cranks and above mentioned RF and CD HG.

    Yeah, many are mucho $ some mentioned are in my budget. I think Id like to stick with Aluminum at this time so Im looking into an XTR setup since it doesn't seem there are other Alm crank arms I can build up in that price range...

    Doesn't look like Ill find any used on Ebay just yet, because someone needs to tell all the people bidding $400 for used/beat 2008-2010 XTR's on Ebay that they can get them NEW for under $400

    SLX arms are within 10 grams or so, throw some Middleburn rings on em and you have a reasonably priced setup.

    Do you mean XT arms? The Weight listed on the SLX triple is showing as 896g's ! I dont see how that large of a difference could be all in Chainrings...

    So do either one way close to that of the XTR arms?

    Just trying to figure out if I purchased SLX/XT arms alone could I use a lightning spyder and lightweight rings for the same weight or less of an XTR setup?

    This would be ideal...

    Ive gotten many recommendations for the XTR Crank to save weight but when I punch the numbers I just dont see the XTR saving me weight.

    Here is the mark according to Price Points "in house measured weights"

    2011 - XTR triple Plus BB = 772 grams + 56 gram Bash - 42t XTR Chainring 60gram?? = 768 gram total

    2011 Stylo Oct triple + BB = 830 grams + 56 gram Bash guard - 85 gram 42t Ring = 801 gram total

    Does 33 grams seem worth a $400 change over to XTR...?

    XTR crank arms are 526g
    + your bash gaurd @ 56g
    + XTR BB 88g
    + 32t chainring 43g
    + 24t chainring 25g
    -------------------------------------
    738g

    Crankset's usually aren't the best place to save weight, unless you spend $$$$. If you really want lighter cranks your best bet would be lightning/specialized, otherwise your going to spend a lot for minimal savings.

    Like I mentioned above - XTR cranks with light chain rings. My Extralite 22T = 16 grams.
    Extralite 32T = 28 grams.BBG makes a bashguard thats 47 grams (oval holes) that fits the XTR cranks.I believe FRM rings are even lighter than the Extralites.

    The Sram Stylo OCT is already a great crank that probably offers the best value of any crankset on the planet. You get the same great long lasting rings as the Noir that are incredibly cheap to replace. And you don't have to worry about hurting a carbon crank, if you live in a rocky area like me. The whole crankset can be had for less than $200 at your LBS if they give you a discount. I was paying close to that just to replace my rings annually on my XTR. My 170mm Stylo OCT 3.3 crankset with bottom bracket came in at an even 800g. I've been told that the Noir actually isn't any lighter. I think Sram posts a lighter than actual weight for the Noir and a heavier than actual weight for the OCT to justify spending the extra money for the Noir. There are lots of pretty and expensive carbon cranks out there, but you will mostly be buying the bling factor vs. the Stylo OCT.

    what rings would you want to put on XTR crank arms? when my original M970 rings wore out I tried middleburn chainrings. I spent ages playing with spacers to get the shifting correctly aligned, but they didnt shift anywhere near as well as the original M970 rings.

    I've got a spare M970 crankset (with worn out rings) that I'd like to rebuild if I can find suitable lightweight & not overly expensive rings,. that still shift!

    So if the SLX arms are only 10 grams over the XTR's why not just buy the SLX arms use my bash, and some light 22t + 32t Chainrings call it a day for 748grams for $250 or so?

    If SLX arms were only 10g heavier, then there would be no reason to get the XTR's. SLX arms are 75g heavier, though.

    Reminds me of why I got the Stylo Oct in the first place, good post.

    I guess I should have asked first if its worth replacing the stock chainrings with something lighter to get the most weight savings out of my current setup?

    172.5mm option and lower Q would still be a reason for me..

    Liking my E.13/Hive SS cranks, by the way. And now they have a nice dual ring setup for the single crank.

    I picked up a sixc carbon recently really cheap, sold the rings and bb leaving me with cost of circa $150 shipped to my door for new arms. Arms are really stiff and lighter than the old m970xtr I removed, really happy with it. Now race face are back in business not sure any blow out stock is around anymore. Good cranks though.

    Okay, thanks to everyone's info, got a pretty great info thread going here!

    I think What Ive decided to do is Keep the Stylo Oct Arms but lighten them with a new Superlight Bash and New Chainrings.

    Ive been looking at the below Rings:

    -Strong light Chainrings
    -FRM rings
    -Superlight Rings

    But cant seem to find the above anywhere online for sale in the US... Also, are the light CNC 22/24t rings holding up for you guys?

    This cranckset could be also an option.

    Products 2011 | BOR - Germany

    It is almost the same design as the tune smartfood. Bor(is), did also design the tune crankset.

    why do you need a bashguard? Run a XTR 2X10 crank (XTR FC-M980, 26/38). Better chainline. lower-q factor. plug and play. No need to triple source parts for various retailers online. Pay. Ship. Install. Ride.

    Has anyone here tried out the FSA K-Force Light 386 cranks? They are pretty light, carbon fiber arms, ceramic bearing BB, and blowout pricing on ebay.

    Personally , I would not ride a crank without a bash for safety reasons. Those big ring cuts are mighty nasty.
