I worked in a bike shop several decades ago. I think it was about 12 or 14 years ago that I decided that I really needed a newer bike, wanted a touring bike. Did not like any of the complete bikes I saw in stores, so I decided to build one up from scratch. I had not been in the bike business for many years so I had to do some research on what to buy because everything had changed so much since my days as a bike mechanic. At that time Peter White had very good things to say about Wheelsmith spokes so I decided to use that brand. Add to that that they are made in USA, which I saw as another plus.

My last wheel set was for a Rohloff bike, the flanges are very wide and some wheels have spoke breakage problems because the spokes take too much of a bend at the top of the nipple. Sapim nipples are designed to accommodate a rim where the drilling is not perfectly matched to the correct angle for the spoke holes in the hub. I only use brass nipples, they say they also have other materials. I saw no downside to using these nipples on other wheels either so I used them on the front wheel too.

If what I buy works well, I stick with it. So, that is why I am sticking with this pairing. I know some people swear by Sapim or DT Swiss spokes, and as far as I know they are good too.

On my last tour, the front wheel picked up a rock and threw it into the rear wheel, then as the wheel turned the rock landed between a spoke and the frame, which put a pretty good ding into the spoke. See photo. And the spoke was quite loose after that. I expected to have to replace the spoke and nipple, which I did not want to bother with, as that would have meant pulling off tire, tube, rim tape, etc. So, first I tried to just re-true up the wheel and I apparently had a lucky day, as a few minutes with a spoke wrench was all that was needed. I mentioned above that I built up one recent wheel with straight gauge 2.0mm spokes instead of double butted, this is that wheel. The spoke length was very very unusual and virtually nobody had DB-14 spokes of that length for sale, so I bought what I could find.
