My bike isn't especially light but it has good hubs. That's my compromise - as long as the hubs work really well, and of course you have a decent BB then the ride is easier than before. I can now testify to this as I had been riding the same bike on what I discovered was a crushed bearing in the front hub and they both needed to be rebuilt and I just said F it! and got better wheels. Now I like riding even more than before!
