I'll take issue with this for a little bit:

Handbuilt wheels are the standard by which all wheels should be judged. The problem is that you just don't know who built your wheels EVEN if your shop tells you that they built your wheels. Many shops just buy some machine made wheels and then tighten the spokes and retrue them for customers.

OK, YOUR shop builds your wheels from scratch. Well, that still doesn't mean they're good wheels because there aren't a whole lot of small time shop owners who build REALLY good wheels. That's why the hand built wheels people have such reputations.

The reason I suggested Mavic Cosmos wheels is simple - they're built with all of the the correct components. Mavic rims and hubs are the very best you can get anywhere and that includes King or Phil Wood hubs. Mavic is the standard for high quality rims. I don't know where they get their spokes but Mavic wheels don't break a lot of spokes though since they are spoked wheels some people DO break a spoke now and again.

But Mavic has all of the BEST machinery in the world for building wheels. They start with straight rims which is a BIG deal. They thread the hubs and start the spokes by hand and then the machine applies huge pressures to the rim to collapse it enough so that the spoke tighteners don't strip the nipple heads as they do on some of the wheel machines out there.

The wheels come out of the machines and are checked and retrued if necessary but usually it ain't necessary.

I have wheels built by my LBS guy and they're really good wheels. But he's been building wheels for 55 years. And his wheels cost a great deal more than the Mavic Cosmos and he's the cheapest wheel builder around.

So, yeah, handbuilt wheels by a good builder are really good, but Mavics are almost as good and you can get them for 1/3rd the price.

And just for conversation - why would ANYONE want disk brakes? Add extra weight that gets in the way of racks and fenders and doesn't stop you any faster nor more reliably than old fashioned cantilevers?
