    Weighed: S Works crank arms (175mm) with Wolf Tooth 32T direct mount ring

    As luck would have it my phone won't send the pic of the scale (please, no neg rep, blame it on Samsung); my friend's 175mm S Works crank arm with 32T WolfTooth direct mount is a total of 407g. Just the arms/shaft/ring, no bolt.

    Comparison: the RaceFace Next SL 1x 175mm crank arms with 30T RaceFace direct mount is 430 grams.

    How does that add up The Wolf Tooth ring weighs 71g in 32t, and the S-Works arms are around 370g with lockring. ??

    Flipping through jotted down notes....

    S Works arms were 337 grams left + right arm
    WT 32 ring = 70g
    total: 407g

    See the notation of bolt: 24g added is 431 grams.

    The RF SL1x is anywhere from 430g to the RF posted pic of the arms, 32T RF ring attached and the adjusting preload collar thingy (word of the day) at 445 grams: Raceface Next SL 1x crankset

    Not that WW takes cost into consideration all the time, but the SWorks were $225 including bottom bracket (local dealer Black Friday blowout) and the 32T ring retails for $79 but he got it for $53 on sale. Total $278 out the door. But MSRP is $300 plus $79 for $379.

    Next SL 1x doesn't come with BB and is $372 at bikeman.com for the arms and about $55 for the ring = $427. A bb is about $45?

    Thanks for pointing out the bolt. I didn't see that. Good price for the crankset!

    Weighed: S Works crank arms (175mm) with Wolf Tooth 32T direct mount ring

    Anyone know where to find a Ti bolt for the S-Works crankset? That's a big chunk of steel!

    I just picked up and installed a S-Works 170mm crankset w/32t Wolf Tooth direct-mount ring. The crank, ring, and complete BB weighed in at 552g (unfortunately this has some +/- to it b/c they didn't have a scale at the LBS and I calc'd this based on the before and after bike weight....the before was completely detailed [clean] and the after was a bit dirty). Assuming the ring is 71g as the WT site states, that puts the crank+BB at 481g. I used the sleeve which, along with the dirt, if you take them out, probably gets me close to the weight westin is showing.

    The "big chunk of steel" is the bolt that connects the two spindle halves. I forget the actual weight but that bolt is significant. If I remember right it is nearly an ounce. A Ti bolt would actually matter in that application, but I haven't found one.

    This bolt in Ti would be a good seller, would likely take the weight of the 175mm arms to 350 grams as I seem to remember it weighing 24 grams.

    No, it does not use a Torx head. But you can use the Specialized tool. For me it works fine.

    Maybe I'm still hungover from NYE, but the total weight savings of the ti bolt vs the stock "big chunk of steel" is about 15 grams?

    That Ti bolt could be lighter... even at 5 grams it's more savings than most Ti bolts will deliver.

    Price is high for that bolt though, anyone find a cheaper alternative?

    Something is strange here. Ti is approx. 50% of steel weight. I checked the weight of my 2011/2012 MTB version Hirth bolt = 20.2 grams. Weights will vary, but not that much on one short bolt. This puts the weight of the Ti bolt about where it should be.
    Marcus, in your scale pics the steel bolt looks much shorter than the Ti bolt. Is the steel bolt maybe from an older Road version of the S-Works cranks?

    I don´t know. That is the bolt that came with the cranks.

    ^^^I think you are correct that that is the road bolt - mine was longer than that like the Ti bolt pictured.

    Anyone have the length of the steel bolt handy? The J&L one available on ebay looks too short (but it is M12x1).

    Its 23 mm not including the head of the bolt. Do you have a link. The only J&L M12 Ti bolts I found are 15mm, but it doesn't list the thread pitch.
