Dia Compe Rear Concave Washer (Bag-10)

Works for mounting rear brakes to bike frames without the flat brake mount surface (primarily track bikes).

Product does not match the image....this seems to be happening with more frequency on Amazon lately.

Since it was very unclear of what I was getting, I wanted to post a comment and say these will work, but they're thinner than I thought and feel much heavier than alloy. Attaching a picture so you know what to expect. This is taken on standard-rule paper so you can get an idea of size. They'll do what I need them to do, but if you're looking for one of the nice thick alloy ones like old pre-80s Mafac and Weinmann calipers arrive with for mounting hardware, you're not going to find it with these. 3 stars for being "good enough", even with the crappy incorrect picture. Package indicates "MADE IN TAIWAN" if country of origin is important to you.

So, I bought these because I needed some, and I thought they were black, which I've never seen before. I mean, the description didn't say they were black, but hey look at the picture. And I have a couple of bikes where I thought to myself, "oh cool, black would look really good on those, and I'll take the regular ones off and use them on another project."But they aren't black, they're just, you know, the regular dull aluminum color.They're concave brake washers and they do what they're supposed to. They're also pretty inexpensive I guess. So whatever.If you're thinking about buying these because they're black, you're going to be disappointed when they arrive. If you just need some concave washers, and you don't care about being the coolest kid on the block because you have black concave washers, then they'll be fine.I guess I could spraypaint them black. But I probably won't. Maybe some other color. 4.9 stars. -0.1 for the boring color, which isn't black.

Does what it should and seems well machined. Gave me no problems.

Works as intended...

Arrived fast and was what I expected, except color. Picture shows black and they were silver.
