I've recently built two sets of wheels with the CR-18 rims. 700c laced to Campagnolo NRs and 650A/26 1-3/8 for the Raleigh Sports. Polished -- I like them. Bought a pair of Sun M13 II rims which are a lot like the CR-18s only narrower. I think they're about 19mm outside width. They're destined for my old Falcon. Built the front and finished it today. Nice rim except at the joint the rim is about 1-2mm wider than everywhere else. No big deal, I suppose. Think it's probably only noticeable while building and truing. The wheel did build fine with good even tension in all the spokes, both true and round.

And then, I worked on my wife's Schwinn and because the air compressor isn't working I tried to gas up the Shrader valve tubes with a hand pump. Broke one of the Shrader valves and then replaced the tubes with presta valve tubes. Nirvana.
