12mm hub to QR - how?

I have accidentally bought a rear 12mm through axle hub (WTB LaserDisc SuperDuty). My bike is Specialized Pitch (Comp) and so far I've used QR hubs. Is there a way to convert LaserDisc SuperDuty compatible with my frame? Or maybe I can even use QR somehow? Would this bit work for me: http://www.chainreactioncycles.com/Mode ... elID=20271 ?

    Have you got an instruction leaflet with the hub? If not, download one.

    For starters that axle converts it to a smaller BMX standard bolt up

    There were no papers in the box, online instructions does not tell if it fits my specialized pitch frame and if not, what conversion or adapter axle should i use.

    What does your frame require? WTB don't know that.

    Looking at this:

    http://www.wtb-bike.eu/data/support/Ser ... DutyV2.pdf


    It does not mention anyything about a 135mm rear hub, or any sort of conversions.

    I don't know that either, that's why I'm asking here. All I know is that it worked with QR before and the frame is Specialized Pitch. I'm sorry for my ignorance but I'm not familiar with frame rear dropout standards and compatibility, especially regarding the diameter of axle. There's not much information available either... specialized just says it's 135 mm wide, but that's not what i need to know.

    You need a 135mm 10mm QR or 10mm bolt up axle hub, and not a bolt thru type ie a standard MTB rear hub.

    I think you need a new hub.

    Wrong, it converts to standard/10mm (I have one) so you can use with any normal bike frame.

    Its a '12mm - 10mm step down axle' 135mm spacing. Just bolt not QR

    I too run a 12mm hub exactly the same as yours, with the above axle.

    If your bike is 135mm rear end spacing with normal dropouts it will work (well, it does what it says on the tin)

    Make sure the hub aint a 150mm lol.

    Or without stating the obvious...return the hub and buy a one that fits. Simples

    it was too good deal to be returned, you can't find sub-300 gram rear 6-bolt hub for 60£ every day ;)

    anyway, I'm going to try that step down axle, hope it works (yes, I have 135mm hub and dropout spacing). Thanks, Big Cheese!

    You mean circa 420g with that axle :wink:
  • Siim_SSiim_S Posts: 37
    with regular QR axle that would be 370 or so, that means it's just some 40-60 grams difference and it's not rotating + I win in stiffness so I'm happy.

    Even though it's Cromo axle material its remarkably light (and stiff obviously).

    But, what you have to remember is that is a bolt up hub so you dont use QR skewers with it ;)

    however the gold nuts I purchased separately. You will get standard coloured ones.
  • Would you mind sharing where exactly you purchased those particular gold nuts from? Thanks in advance!

    I got mine from CRC, made by Gusset.
