I have them, but I need to service my hubs (accidentally bought 10-15 year old NOS hubs when I thought I was buying modern hubs on the e-bay) and install the cassette before I mount the wheels. Don't have a scale, so I'm not sure how much they weigh. I live/work in a relatively low crime area (more casual bike thieves than pros), so I was hoping this would be a more convenient (and lighter though I ride a drop bar converted steel mtb with font and rear racks so I'm not much concerned with weight) way to secure my wheels than the long 12 mm cable I use now looped through my u-lock.

Just by hefting them they're maybe a little lighter than the quando skewers I pulled from the hub but I doubt it's significant.
