Are you familiar with Mavic A319 rims? Are they decent for a cheap, non-aero rim? I was going to build myself up some wheels for a geared townie bike for my wife with sun cr-18 rims and tiagra hubs, but I found someone online selling a new mavic A319/tiagra wheelset (supposedly handbuilt) for cheaper than I can source the cr-18s and hubs, let alone the spokes or time (this would have been my first wheel build, but I also have the parts to build wheels for my bike over the winter).
