9mm fork dropouts 15mm wheel axle

jsisidore

Thus I need adapters but have no clue which ones. 15 to 9qr would be a rational choice I suppose?

jsisidore

Ordered this one. Hopefully it's what I need.

Assuming you have Nukeproof hubs, probably.

I've got that one. Works with any hubs, not just Nukeproof ones, and does just what you want it to.

That is what I thought thanks!

I'm confused. The adapter has arrived BUT the inside diameter is only 5mm whereas it was advertised 15mm to 9mm QR. I bought a dt swiss 9mm thru bolt and obviously it is too big for the adapter. What's going on?

That's correct. The axle is 9mm diameter. (10mm rear)
It is hollow take a 5mm skewer.

The Rookie

The ends of the adaptor will be 9mm to fit in the dropout, the hole in the centre takes a 5mm diameter skewer.

You need....

You should of mentioned that you were using a 9mm thru axle.

Or one of these http://www.ebay.co.uk/itm/FRONT-WHEEL-S ... 0JVkFljqQA which is what the original adaptor was designed to work with, surely?

The Rookie

As a 9mm through axle won't fit into the 9mm QR forks (thus totally defeating the object of the adaptors) that would seem to be an exceptionally stupid suggestion, just need the QR skewer as Larkin says.

or exchange the adaptors for some suitable for use with the 9mm dt swiss axle the op has bought.

You should be able to get some as all the big hub makers hope, dt swiss etc make them for a 9mm through axle.

The Rookie

Who said he has a DT Swiss hub?

I thought the 9mm thru axles are threaded and so screw into the frame so n/a for forks

The Rookie

Yo can get forks, but usually gravel bike style for 9mm through axle (ignoring the non OE fit screw threw upgrades).

jsisidore

Now I'm confused. But I did bought the 9mm thru axle, I kind of want to use it but that means I have to invest in yet another adapter? I better keep the 5mm one I guess. I don't regret all these complications, at least I'm learning a lot about how convoluted the cycling industry is

larkim

I think you need to clarify what the dropouts in the forks that you have got are, and what the wheel is designed to take.

If you've got forks designed for a "standard" QR skewer, then no thru axle will fit it (thru axles generally screw into one side of the fork, so that side would be threaded) and you'll need an adaptor to convert whatever size the wheel is designed for down to a QR. If this is the case, the 9mm thru axle that you have is no use to you.

apreading

I think the OP has 9mm dropouts for QR skewers.

This image may help:



Note the dropout is 9mm, because that is the diameter of the end stubs of the wheel hub. But (obvioulsy) the hole through the middle of those stubs is smaller than 9mm. They have a wall of around 2mm, leaving 5mm hole for the skewer - this is a standard QR skewer size.

You can get 9mm axles for the front but a) they are not common and b) they are not what you want in this case. The skewer needs to be smaller than the dropout for the end stub of the wheel hub to be accomodated.

Hopefully that makes sense?

Are you SURE about that (think carefully - or even check - before answering)......

You can get 9mm bolt through for 9mm QR forks but it requires the right type of front hub to use it and is of minimal benefit.

I guess that jsisidore could get the adaptor drilled out to 9mm which would accept this style, but the stiffness benefit is marginal in the extreme.

larkim

OK, I was over-simplifying! (Doh!) It's a terminology thing, i wasn't really considering a 9mm QR to be a thru axle, but on reflection I suppose it does qualify.
