Dumb wheel buying question

'Scuse my ignorance in advance, but...

when looking at wheels on Superstar's site, for front hub adapter choices they list "QR" and "9mm", are they not the same thing?

:?

    Yes and no.
    A qr front axel is 9mm (or 3/8") but then there are some 9mm through axels or solid axels.

    You can have 9mm QR or 9mm solid axle with nuts on each end, fit in the same dropout, nutted are more often seen on jump type bikes as the axle is stiffer and the nuts have a slightly better stiffening effect on the fork than a QR, that said proper jump bikes will be 15 or 20mm anyway.....

    standard QR has a 5mm axle the 9mm has a 9mm hole that you can thread a 9mm QR axle through. you can get a 10mm version for the back.

    no nuts and bolts involved

    Ok, now I'm confused. I thought my standard QR front skewer was 9mm, to fit the 9mm dropout in my forks? Nicklouse and Rookie seem to be agreeing with that, but you're saying it's a 5mm axle? I don't fancy going out to the garage and getting my vernier out, it's cold out there...

    I'm now also confused about the rear too, lol. I believe my standard rear QR is 9mm? So from your links am I right in saying that on the rear I could choose the 10mm hub option, buy one of those 10mm skewers and it would still fit in my standard rear QR dropouts? Or am I getting this all arse about face? :?

    Further confusion. My standard rear QR is 10mm?

    That's what i thought, until somebody mentioned 5mm. So if my front's 9mm QR, and my rear's 10mm QR, why do superstar list QR and 9mm (front) plus QR and 10mm (rear) as separate options (surely it makes no difference to the hub I.D. whether the axle is QR or both through?), and which do you order for a standard 9mm QR dropout fork and standard QR dropout rear? Confusion abounds in my noggin... :?

    The skewer is only 5mm diameter for QR. The axle which fits in the drop outs in 9mm, the skewer goes inside the axle.

    I blame the industry for it's stupid naming tactics, though I think some people here are being a tad awkward with their explanations, which whilst technically correct, haven't helped answer the question. nowadays qr means qr in the tradition sense and 9/10mm refer to bolt through axles, as they do with 15/20mm

    I see, I did wonder if that was what was meant above. So on my OE front setup the diameter of the skewer itself is 5mm, but this goes through a 9mm axle which locates in the fork dropouts. So does that axle pass through the hub, or is the I.D. of my OE wheel hub 5mm? In which case, if I was buying new wheels then I'm guessing the best (i.e. stiffest) option would be to order the 9mm hub and one of those 9mm QR skewers (and that if I ordered the QR hub option then it would only fit 5mm skewers)?

    The O.D of a traditional Qr hub is 9mm, I.D is 5mm as you say. The 9mm thru axles from superstar and others have an O.D of 9mm so effectively act as the axle of the hub and the Qr in one, so you can use existing qr forks. I had a DT swiss 9mm thru axle with some old wheels and they definitely made the forks feel a little stiffer. I've still got it somewhere I think, I've no use for it as both bike are 15mm now, the DT ones are quality, half the weight of the superstars, think they're like £45 retail!!

    Right, I think I've got it then. So if I was buying a set of wheels to fit my Kraken (avec new 9mm dropout Epicons) the stiffest option would be to order the 9mm hub option and buy one of the 9mm QR skewers.

    Similar story at the rear? OE QR and hub ID are 5mm (but in 10mm dropouts), so best option at the rear would be order the 10mm hub option and a 10mm QR skewer?

    Lol, thanks. Sorry for being a dumbass. A few minutes in the garage with my vernier would've answered it for me, but it's not really garage weather right now.

    Easy to get confused! At least you didn't try and convert a 26er to a 29er!! :lol:
