I would trust the velomine set a LOT more than the others. Bike shop "replacement quality" rims are pretty dismal until you spend a little. Heavy, and very wide/soft alloy which is usually non eyelet single wall. They're almost hybrid width, as well. "New" wheels that are under $120 a set are worse than what you have already, and will not stand up to daily commuting. Riding with a missing spoke, you're about one hard bump away from disconnecting the brake cable to get home. Also seven speed freewheel rims are likely to snap the rear axle when subjected to curb jumping, potholes, etc. I am sorry to be so cynical about most of the "new" wheel offerings, but most are twice as bad as the wheels from back in the eighties. Just personal experience from three years wrenching in a bike shop (2010-2013),,,,BD

Most replacement wheels that say 27 x 1 1/4 mean exactly that. The rim is actually 1 and 1/4 inches wide, which is huge if you think about it. Most 27's back in the day were about 3/4 to 1 inch on average, no matter what the size stamped on the rims. The new wheels seem to take the rim size literally, instead of going by what tire sizes fit on the rim.
