Brake makes noise where wheel joins together...
Hey folks.
I just bought a brand new CAAD10 and I'm loving it. Only have about 15 miles on it over the last 4 days (I know, not enough) but I've been a little hectic at work.
Anyway, the two times I took it out for a spin, I noticed that when I brake the front wheel, it will make a noise after every rotation. I happened to then figure out that where the one piece of metal merges on the wheel, it's not perfectly flat. Now I thought maybe one side was higher and the other lower, but they are both wide.. Thus the noise. What gives? Anything I can do? Should I contact Shimano? Not really wanting to file down my new wheel if you know what I mean.

Too bad you don't want to file them down....because that's how you're going to get the noise to go away. Sorry.
The braking surface will wear down over time and the sound will evetually go away as your brake pads lap that joint, but a minute and a file and scotch brite pad can make it go away now.
Common - FWIW.

This happens to me too!! I just got my first roadie last week.. a Caad8 5.. The wheelset that it comes with are Maddux RS 3.0 Speed rims laced to formula hubs.. (the hub is quite a good quality hub tho) but the imperfect rim is on my rear wheel.. i hardly uses the rear brake so it is almost unnoticeable. I think it is quite common for a low quality wheelset or sometimes to the pinned rim (not the welded rim like those high end wheels). I did more than 300 km on the bike now.. i guess.. and the noise is not as loud now..

That being said, I'm surprised a new bike is doing this. They have been machining the crap out of rim seams for quite a while now.

I would take it back to the shop for them to have a look and file the frame down if needed then there shouldn't be any issues with the warranty.

IMHO, This is a warranty claim - pure and simple.
Take it back to the LBS where you (presumably) bought it, and have them fix it. They'll probably just swap out the wheels with another new CAAD10, and send yours in to Shimano for a replacement.

Wow....crazy. Really guys?
Rims are machined at the joint without having been spoked or tensioned. If the rim joint is anything other than massively welded (say pinned), then the rim has the potential of having the faces of the joint move under tension. On cheap/OEM wheels the rim quality is such that this is a higher potential.
It doesn't affect the quality of the rim, or the quality of the wheel or the build. It just bothers an occasional person.
5 seconds and the problem disappears.

My bike shop happens to be an hour away, that's the unfortunate part. NOt really sure if thats worth the trip. Does no one else file them down except Psimet2001?

I've always just put up with it, but next time it happens I might try Psimet's suggestion.

The last time I had this happen, I filed it down. The only problem was I overshot a couple of times and sanded the sticker a tad.

The few times I've had this situation, I've touched it up with a dremel with a fine grinding wheel. I just touch up the trailing edge of the seam. Yet another use for a dremel tool.

OP, it seems a bit scary taking a file to your new bike. But realize as stated above that you're just accelerating a process that the brake pads, and road grit will eventually do over time and it's not that scary.
Use a fine toothed file, and go lightly at first. You'll be fine.

File it. A good mill file is not expensive and is flat. Anything else such as a Dremel or sandpaper will follow the bumps and not leave an even and flat finish.
