I received a front wheel built with an Open Pro rim from a customer (Ninja).

Even though it's called an Open Pro, it's actually a 650C rim.
I'm going to rebuild this into a 700C Open Pro.
I can't move forward with transferring components to the 700C frame without doing this.

This is something I built a while back.
The hub is a Shutter Precision dynamo hub.
Maybe I should clean this up a bit more

Got it built.
The rim is used—it's one I used to have.

32H all-Competition lacing, Italian-style cross pattern.

I went with brass nipples.
Since the Open Pro has brass double-eyelets,
I could come up with some made-up reasoning about considering the potential difference between the nipples and rim,
but honestly, there aren't really any cases where you actually need to worry about potential difference when selecting nipples.
The real reason is just that it's a commuter bike, so this should be fine.
