    Lite but rigid crank recomendations
    I've 2 ideas but looking for something comperable. I like Tune smart foot & Extralite e-bones w. Anything out there close to weight & price?

    If you've got a BSA 68mm bottom bracket then its hard to go past the Specialized s-works cranks with E-13 (or similar) BB.

    They are super stiff and light and probably cheaper than the Tunes / Extralite:

    I'd like a set of those myself, are they still back ordered?

    I got mine off the USA speci store about 4 months ago. They had 170mm and 175mm in stock. What does the store say?

    It says 180mm are available. I couldn't find any online retailers stocking these.

    I think they are pretty much only available through the speci USA online store and speci dealers. Its a shame they don't make them in greater quantity and more widely available.

    I was considering Rotor 3D+ or maybe Cannondale Hollowgrams, but as you say its hard to go past the Specialized s-works cranks.

    One thing that leaves something wanting is the lack of user reviews or long term durability reports. I'm 190lbs. and I drop and jump (small stuff, granted), I've not heard of any rider weight limit or intended usage. Perhaps that info resides in the Specialized forum.

    To the OP, sorry if I hijacked. here's an interesting discussion that has some decent suggestions and info relevent to your inquery-

    I've got 2 years on my S-Works cranks running on an XC/AM bike and they've been excellent - really stiff and no issues. There is no rider weight limit on these as they are OEM on Spec. S-Works bikes.
    Wish I could find someone to make me a 5mm Herth spacer so I could run these on another bike with a threaded 73mm BB.

    Thanks xc71!

    I did not realize that these could be run on a 73mm BB even with the Hirth spacer as I thought the S-works cranks were a 30mm spindle.

    They are a 30mm spindle, for 68mm BB you simply remove all spacers & run 30mm threaded cups from Hive, Rotor, Zipp, THM, etc. Wave washer on the non-drive - works awesome.

    Ya roger that, when you wrote threaded 73mm bb I falsely assumed you meant an English bb.

    I have a 73mm bb so the s-works are out, has anyone had experience with KCNC, they have a crank set w/bb that suposedly 714g and that is with the double cobweb chainrings that look pretty sweet.

    I'm confused.. does this mean that you can run these (or ANY BB30) cranks in a standard threaded frame using the 30mm threaded cups?

    Not sure about ANY BB30 cranks, but certainly the speci s-works - if (and only if) you have a 68mm BSA threaded bottom bracket.

    68mm BSA is pretty much the standard for threaded BB's, No?

    So it sounds like any BB30 crank should work in these cups as long as it is 30mm spindle?

    Also, Speci website says these will work on any 73mm BB30 shell, so why not on a 73mm threaded shell?

    OP, sorry to hijack the thread, but I think this info could be extremely useful to all of us who have felt our high-end crank options limited by threaded frames.

    To me, the Speci Sworks look like the best bang for the buck.

    73 threaded BB is also common.
    What you are seeing on the Spec. website is a PF 73 BB ( bearing inside the frame). A 73 threaded BB has the bearings outside the frame, therefore the S-Works 90.7mm axle is to short by 5mm for a threaded 73 BB.

    Where did you get that and how much did it cost if you don't mind me asking. I've been looking for that piece for almost 2 years now.

    I wanted to use the s-works cranks on a BB92 frame so i took all the measuring and asked a lathe operator to make the piece. It costed around 50. i don't have it anymore, i sold it to a very well known bike parts manufacturer!

    Anyway, if you have the cranks, just go to a good lathe operator and ask him to make it. The spacer's width is 5mm!

    Hope i could help!

    Thanks for the info David. After I got mine to work on a 68mm BB, I took the cranks to two fabricators in hopes of getting this to work on my 73mm BB bike. The first fabricator wouldn't even touch the job & the 2nd said it could take up to a full day on a CNC machine to get the spacer perfect ( which it has to be) @ $275.00 per hour.

    The S-Works crank is a licensed copy of the Lightning crank. The S-Works is cheaper but the Lightning is available with axles and bottom brackets for all BB shell types and in 3 levels of weight/strength/stiffness. They have many different spiders that also fit the S-Works including what I believe is the only double ring spider that accepts a bashguard. I've had the HD version on my FR/AM bike for 2 years. Many enduro races, resort runs, DJ sessions, and 1 foot landings later they feel like new.

    That's way too expensive! This guy made it by hand on the lathe and it fitted perfectly! I wound not mind of asking him to make another one and send to you but i don't have the cranks anymore.


    yes MarcoL, Mattias has got it now!

    If someone makes this spacer (Mattias...) I'm in for one, maybe two. Can we get anyone else on board? Or start a new thread here...?

    That would be fantastic David if you can get ahold of some cranks. Thanks very much.

    Is the spacer in question in the middle of the cranks? the toothed piece?

    I have a manual lathe but that looks like quite a challenge. Does anyone have a drawing of the piece?

    Yes, its the 5mm toothed piece in the middle on the axle spindle. Skill testing venture as there's zero room for error.

    My Lightnings for a BB92 frame actually came with a similar spacer. However, Lightning uses different shaped teeth so it's not compatible with S-Works.

    Ok, before I try to hijack this thread (sorry!) I'll say that I've been riding the S-works cranks on my Niner Jet 9 RDO, which has PF30, for the past 6 months with no issues, and I absolutely love them. They're 480g including cranks, crank boots, Lightning reversible spider, and 22+32 Extralight chainrings. FYI, the granny chainring bolts hit my frame when the spider is in the double configuration, so I'm running just the 32 in the high double position currently, with BBG superlight on the outside. I'll hopefully be flipping the spider over to the triple side this weekend, and we'll see if everything fits.

    Now, I just picked up a road bike frame with a BB86, and I desperately want to use the less expensive S-works cranks (road or mtb version is fine with me) so I don't have to shell out the money for Lightnings. From what I'm hearing in this thread there's a remote possibility that the s-works mtb cranks might just be long enough, assuming I can get some 30mm ID bearings that will fit into the BB86 cups. If BB86 is 86.5mm wide and s-works mtb cranks have 90.7mm length spindes, does it follow that they might just fit?

    Rotor makes their UBB30 cranks that fit BB86 frames, so they must have 30mm ID/~40mm OD bearings they're using. I'll be calling Lighting later today to try to figure out if their BB86-compatible cranks have 24 or 30mm spindles. They mention that the bearings are provided, so I'm guessing they do this because they're 30mm ID and normal BB86 bearings are only 24mm ID. I don't have the frame in my possession just yet, so I can't size up the BB with my cranks yet.

    You might (probably) have the wrong spacers behind the granny ring. There's different length spacers for running the spider in double and triple configurations. Measure your's and call Lightning.

    I appreciate the tip, but I should've mentioned that I actually have both sets of spacers&bolts. I originally ordered the 12mm bolt/5mm spacers with the spider to run it as double and found that they hit the frame. I then ordered the 16mm bolts/9.1mm spacers for triple config, but lost the spider lockring tool before I could flip it. Now with a new lockring tool in hand, I just flipped the spider with the help of my mechanic's vise. I'll report back on whether everything fits. Also, I think user xc71 had a very similar problem with the chainring bolts, but he is using external BB cups, so he just filed them down enough for the bolts to fit.


  • 02-08-2013

    My issue wasn't the bolts hitting, but the inner most part of the 22T Extralite chain on the external outside diameter of the threaded cups. The cranks still turned but it was just slightly touching. I just removed a couple of thou off the cups.
