I need to replace a rear rim on my bike. Currently I have a stock ARCH wheel build from no tubes with a DT swiss 240 hub. I dont know exactly what spokes came on that. I think they are a 2.0/1.7 Butted spoke (not exactly sure what thats telling me).

I would like to rebuild this wheel with a new ARCH wheel and a new set of spokes. Ideally I would like to take a small step up in strength of the spoke if possible.

Any recommendations for the spokes on this wheel?

I like 14/15/14 for rear wheel applications, only a few grams heavier and I feel they build a stiffer wheel.

I have a new white arch rim (32h) hanging in the garage if you need a rim. Half-off whatever they are retail plus $10 shipping. :D

all commonly available spokes from reputable manufacturers are sufficiently strong, and the strength of a wheel is not directly tied to the spoke diameter as you might think.
2.0/1.7 double butted means the spokes are 2.0mm in diameter at both ends and 1.7mm in diameter in the middle.
AFAIK only Wheelsmith makes a spoke with those dimensions (of the three spoke companies I trust), and they are easily distinguishable two ways: by the "W" stamped on the heads and by the butt, which is a "step-down" and not tapered as much as DT or Sapim spokes.
SuperComps are triple butted: 2.0mm at the elbow, 1.7mm in the middle, and 1.8mm at the threaded end.
I see more problems with S.Comps than any other spoke by a large margin.
Spending the money to reduce the threaded end diameter doesn't make much sense to me.
I don't know what the reason is for wanting to "take a small step up in strength of the spoke" is, so I can't really address that.
Thicker spokes build marginally stiffer wheels, but 1) stiffness and strength are not the same and 2) the difference between a 2.0/1.7 and say a DT Comp or Sapim Race (2.0/1.8) is not something I think you'll notice.

Edit: Wow, this is an inadvertent repost of most of the info MF provided.

The dimensions of the double butted spokes you have are in mm: 2.0mm x 1.7mm x 2.0mm. This means the hub and rim ends of the spokes are 2.0mm, and the butted middle section is 1.7mm. These spokes are a good match for the Arch rim and the 240s hub. The rim is the weak link in your wheel, unless you are over 185 pounds in weight or are riding these for mostly AM conditions. I know that NoTubes had some QC problems with their wheel builds in the past, so that may have affected the strength of your wheel. Think about getting it rebuilt by a quality wheelbuilder, and/or getting a stronger rim to increase your wheel strength.
