pretty looking, or pretty stupid?off roadie

I built a new front wheel for road bike. Wanted low weight, had 34 2.0/1.5 spokes (ordered 50, used 16 on back nds) that I thought would fit laced 2x. They ended up a bit long, but my beer-enhanced "skills" made me confident a twiseted spoke wheel would work.

Actually turned out pretty nice. Spoke angles are almost exactly what they would be with 3x, and I got the tension up to exactly what was neded to produce Brandts "mini taco" effect. That was suprisingly low tension (about 85kgs) but I suppose that's how it goes with road wheels. Seems a good tension for a 1.5 mm spoke anyhow.

The twists seemed to "set" very well, and repeated stress releif doesn't result in any loss of true. Overall it seems like a nice build. Time to go out and ride it! Its dang light, just right for hill climbs, where the extra stiffness could help, and the "bad aerodymics" won't matter.
It looks strange to me and I have a question if you don't mind..divve

During inspection I found out yesterday two spokes used on the drive side of one of my rear wheels are too long. The build is CX-Ray, OP rims, Record hubs. Will it be okay to replace those two spokes one at a time or will it be necessary release the tension on the wheel to replace those spokes? Thanks.

It's OK to replace your spokes one-at-a-time without detensioning the wheel. It won't create any problems.

Since you found two too long spokes on the drive side of your wheel, I'd check the nipples on the non-drive side to see if I could see any spokes with exposed threads. Rear wheel spokes are commonly a millimeter or two different in length between the two sides. I'm wondering if your wheelbuilder got his spokes intermixed. You may already own the spokes that you need to fix your wheel.

Thanks for the info. I already checked all spokes and talked to the shop who built them. The reason for the two longer spokes was price. The shop thought they were doing me a favor by not having to buy a complete pack of 20 CX Rays just to get two extra spokes...

There's not a lot more to show. Each of the 16 spoke pairs being more or less identical, which makes for a booring photo essay. Its a round wheel, eh? :)

Here's a shot showing the overall layout / profile view.

I've read about twisted spokes in Brandt but never seen it in real life. Congratulations on having the guts to try. Theoretically it should be pretty stiff.
