    Colours uses Xcores but they are 1/2" dia.

    Found X-Core's site -- here's some info.

    XCore 3 - http://www.x-corewheels.com/media/nwhubdwg.jpg
    Width (see technical drawing). Tip, want to measure the hub of your existing chair? Insert the quick release axle into your hub and mark with a marker on the axle where it extends through opposite-side bearing. Now remove the axle and measure and compare to our hub numbers. Sometimes it is necessary to get new quick release axle, see your chair provider for assistance.
    Bearing bore (most US chairs have ½”, most euro chairs have 12mm)

    You all are such legends for helping me out.
    Thanks a bazillion.

    Can an experienced brain just confirm for me :
    Axle I need will be same as the size in jadis' picture, Rougly 111-113mm (quad hand margin of error). Do I then order the 4.5 inch length axles and adjust them shorter?

    Any glaringly obvious error in this logic?

    Thanks again

    Thumbs up

    AO,
    I hate to make this harder than it already is BUT....
    When I look at her picture I see 110cm as you measure from BEGINNING of thread to start of ball. I used my mouse icon as the straightedge. Which would make it 4.33 inches. Now allowing for nut to back OUT making it longer, this would work with 4.25 inch AXLES.
    So the 4.5 inch axles would be too long from the get go.

    Between me and you, if you order the 4.5 inch length, I can make you spacers on my lathe to take up the .25 inch difference. If they are too SHORT you would have to send them back. NOT COOL, we want ya on them wheels ASAP. Email me your address and I'll ship ya a pair of spacers so they will be there in case you need them. It's been too long already.

    Hope I haven't corNfuZed ya. I'll get to making the spacers here when I get going tomorrow. It's 220am here now.

    I sent an email to them Phil. QUESTION. Are you measuring from thread to ball(NOT) including thread length?? this is the way.
    DON'T include the length of thread. Think of it as Inside Distance-edge of thread to edge of ball.
    The thread length gives you EXTRA length.
    And when you install them, you want at least ONE WHOLE THREAD extending past end of nut.
    They should email me back in the morning.

    here is an online metric-english converter

    We'll get it straight in a few hours I hope!

    LMFAO!!

    This is crazy I've been measuring from the outside of the thread, it seemed to make sense at the time.

    I need a length of 110mm-113mm (4.33 - 4.45 inches) to fit the width of the hub plus the housing bracket in the wheelchair. That would be the measurement from the bottom of the nut to the inside of the ball.

    * Looking at the diagram on their page again, it looks like they are measuring to the outside of the ball too, which would then offset the width of the thread by about half so maybe the 4.5 inch will still be ok?

    i r Confuzzled

    Maybe this will help someone else out in future too.



    Trying to show the 'usable length' - the area I define as inside of ball to edge of nut GREEN, YELLOW, TURQUOISE lines

    So if I need 4.37 inches I need to go for AX22 or even AX20?

    SLAP ME somebody! QUICK!
    I was WRONG Phil, measure ALL of the thread to beginning of ball.

    Thought about it, makes sense to me, where did I come up with my hairbrained scheme.....even though it makes more sense to me my way, as only the part from inside the nut is actually usable. If I were to go by the WORDING, I would use inside length- nut face to bearing edge...but hey, I just think logically

    I still haven't received an email from them, just wanna be absolutely sure they measure same way.
    Got this from those high dollars at sportaid

    http://www.sportaid.com/catalog/page...elchair%20Hubs

    BTW was checking out your 'MY SPACE' page last nite, thot u were an old man fer som reason, LOL!
    I gotta put me one of those up sometime.

    I gotta go put some time in on the old handcycle.

    Talking email by PONY EXPRESS lol

    John,

    We measure from the ball to half way through the threads, or useable area.
    I think Phil has it right with the AX22. It is adjustable both smaller and
    longer about 3/16 or so either way.

    I'll send them soon and we'll find out for sure.

    Thanks,
    Leonard

    Do ya measure from beginning of ball to start of thread(ID) shorter
    or from beginning of ball to end of thread (OD)longer?
    Asking for a buddy in South Africa who is a quad and having difficulty. He
    thinks 110 mm length is needed
    I'm verifying this before he orders from you. and asking him about his
    measurements to be sure. I am going to make spacers and send just in case,
    we would rather order long than short. Thanks a million, btw it's for a set
    of xcores trying to install on a Tilite ZRA.

    AND THEY MEASURE YET ANOTHER WAY lol

    Hey Phil,
    If it were me, I'd order the AX20's with a 113 mm axle, once again better long than short.I don't think that there is enough adjustability in the 22's to safely accomodate 113mm. I'll send ya a couple different sizes of spacers just in case, if you order the AX20's if you want. Let me know what'cha wanna do.

    you will notice in the picture that at 4.375 inches, it is fully extended, and you REALLY need at least 1 full thread extending beyond the nut for safety. Therefore, if ya measured just a tad short, you're hurting.
