These wheels use good components, the Shimano 105 hubs and Velocity rims are excellent! They do need some love though...
When I receive them, the back wheel was significantly wobbly... To the point they wouldn't roll because of break rub. That was about 5-8 mm off. Front wheel was perfect. Once trued, I went for my first spin. About 30 min, 8 miles with some fast moments (30+ mph), sprints and small hills.
Once back I noticed the rear wheel slightly out of true... So I began tuning the wheels. That's a few hours of work with great attention to detail. Here's my process, based on "Professional Guide to Wheel Building" by Roger Musson (
Oil nipples
Stress relief by squeezing spokes
Lateral True
Check for dish
Check and adjust for even tension (plucking each spoke for tone) balance tension in 1/8 to 1/16 of a turn increments
Increase tension by 1/4 of a turn increments on each spoke
Stress relief
True
Dish
Pluck
Increase tension
Repeated a few more times. I increased tension on those wheels by about 3/4 turns.
On to my second spin the next day... Wheels felt more rigid and were true for the ride. Ride felt smoother than with my previous wheels with same tubes, tires, and air pressure as before. They roll very well.
When going back home, I hit something really hard with my front wheel at about 17 mph... Couldn't tell exactly what it was, I had to focus on traffic... It damaged my front tube (I had a flat)... But the rim was intact and the wheel perfectly true. Definitely a quality set if tuned properly.
Note that I had similar problems with a 29er Shimano set I got for my hybrid. Great wheels but also under tensioned. Perfectly trued out of the box but needed to be aligned after first ride.
