I have tried my LBS (local bike shop) and looking online, but haven't had much luck with this. I need a replacement rear wheel for my Cannondale Topstone Sora. It is thru axle, 12x142mm, 700cc, 9 gear Shimano cassette. Any suggestions?
One other important piece of information needed is brake style: I'm assuming disc brake given the thru-axle but is it 6-bolt pattern or centerlock?
Also do you know the rim width? It should be marked on your old wheel with 622×W where W is the width in millimeters.
I also work at a shop, so I had a look through our wholesaler's catalogs and that's where the real problem is, there just isn't many wheels available with your specs. Like, our shop couldn't even place a backorder right now if we wanted to with ETAs listed of December for us to even place an order, until you get into some expensive ones. So I'm guessing your LBS was just offering you the cheapest they can even find right now...
Wish I had better news for you, but looks like you're just gonna have to keep a look out with persistent searching.
