    How is this design any better than the prior S Works carbon crank with a direct mount ring? I can see how maybe it'd be lighter with a 2x ring setup though.

    That´s the reason for my question. If they are not lighter I can stay with the old one.

    They also lose the "ultra-torque" setup (split design) which should aid setup.

    My take on the molded carbon spider and arm is that it offers big gains in stiffness. This together with the mega chain stays on the WC, the much larger frame structure around the BB, all add up to gains in drive line efficiencies.

    Weight savings will be in the spindle and crank, just like what RaceFace accomplished on the Next SL. The new molded SW spider won't offer any weight savings as it is very bulky by comparison to an aluminum spider. The specific gravity of solid carbon is about the same as magnesium which is about 30% less than aluminum. But a visual estimate of the spider looks to be more than 30% larger than aluminum, hence my weight saving estimate of the spider portion will be nil.

    The spider could have a structural core of foam to lighten and add stiffness for the weight, but this has not been mentioned in literature so far and I would think this could be used as a marketing advantage if it were so.

    OK class, too much speculative analysis . . . lets go for a ride!

    Which looks to have a stiffer spider/ring combo?
    New SW by a big margin is my take.

    I had my heart set on the Next SL for my WC frame build, but not so sure anymore. Weight isn't everything.

    Last years SW cranks, spindle, rings, BB = 656gr
    Next SL with 34t and Raceface BB for PF30 = 551gr
    XX1 with 34t and Sram BB = 641gr
    New SW cranks with 34t = ?

    Are those actual weights?

    My SL 1x arms/spindle with 30T was 420 grams. The 34T setup is 445g. A BB weighs about 80 grams?

    My current model S Works with 32T direct mount and bb is within 10 grams of the SL 1x.

    But as stated weight isn't everything. Were some riders complaining the current S works crank not stiff enough? On an FS how would one even notice a difference factoring in rear shock and tire deflection? If it's for change or marketing I would not go with the current logo on my non-Speci bike. But Speci's pricing has a big advantage ($160 diff for my S works vs SL 1x purchases) over RF and not too far off from the heavier XX1.

    The old SW cranks 2010?-2013 and still listed on Spec site weight that I quoted were for the 2 x set-up.

    The Next SL weight is taken from RaceFace. Their PF30 for these cranks is shown at 101gr.
    Nice to have your weight with 34t at 445gr.

    The XX1 is my weight.

    I misplaced the weight on my 2011 SW cranks with XX1 spider and XX1 32t.
    But I just weighed the SW 2011; spider, 2 rings, bolts and spacers = 186gr
    The SW XX1 spider is 43gr and XX1 28t is 34gr = 77, which is only about 10 gr more than a Wolf direct mount. So then the SW cranks with XX1 and BB is about = 547gr. This matches your calculation pretty close.

    So then the Next SL setup is not a weight advantage after all.


    But you are right, can we even tell if the old cranks and frame are not stiff enough?

    Only one way to find out, ride a WC back to back with a SW 2011-13.

    No, definitely the SL 1x is not a weight advantage. The advantages are in 1x chain rings of 28 and 30T which for some is huge.

    How's the saying go? "A fool and his money are soon parted." Is that $800 US dollars.... or some other currency that translates to about $300? Did it come with a year supply of EPO?

    Just weighed my 175mm S Works crankset (the current version) with ring and bb.

    Two arms 185 + 155 = 340g
    Lock ring + parts to attach chainring and join crank arm bb spindle: 36g
    Wolf Tooth 1x 32T direct mount ring: 70g
    BB cups, bearings, 73mm spacers, wavy washer minus center sleeve: 74g

    Crankarms, 32T ring and all necessary parts: 446grams
    RaceFace Next SL 1x 30T and XTR 985 1x setup weights compared: Raceface Next SL 1x crankset

    Grand total for a 175mm S Works crankset with 32T ring and Specialized 73mm BB setup: 520g

    Thanks for weighing that out.

    The Spec BB cups and bearings are lighter than I thought at 58gr. +10gr for missing sleeve?

    So Next SL is about 45gr heavier at about 550gr as they require their aluminum BB at 106gr do they not? The external cups use up the space created by the straighter cranks as compared to XX1 or SW. You can't use a SW BB with Next SL unless you install a bunch of spacers. Am I correct?


    Found the answer. Raceface has an adapter/spacer part F10010 to use other brand internal cupped PF30.

    Center sleeve is 28 grams.
    I'm not 100% sure on the RF SL 1x spacers (see now you found it) and I was going to run it on my bike, but the SW came with the BB so I just went with it. Fingers crossed it stays quiet and reliable with its non-metal cups.

    Last time I check, it wasn't available on it's own. Anyone have any luck with the new Control SL?
