I busted up my old 9mm QR front wheel pretty bad. I was able to get a new wheel, but didn't realize it was a 15mm axle, and now it won't fit on to my fork.

I really really want to try this wheel out. Is there any kind of 15mm to 9mm adaptor that I can get?

Or is my only solution getting a new fork or hub?

Depending on the brand of hub, there may be adaptors available. If not, getting a replacement wheel would be the cheapest option, changing the lowers will be expensive, and changing the hub would involve a wheel strip, replacement of all spokes, and rebuild, which will end up costing far more than a replacement wheel.

What hubs do you have ?

There's some other brands too.

Do you have a 9mm skewer or does your old hub have a 9mm axle that uses a 5mm skewer?

Can you return the wheel and get the appropriate one?
