I bought a 13-28 SunRace about 3 years ago. It felt a little rough and started "grabbing" after a few miles. I took it off and back to my LBS for credit.
Back in the mid 70s I had a Regina Oro FW lock up on me on a long fast descent. Fortunately I was able to safely stop and inspect the problem. I babied it with the brakes the rest of the way down then rode "fixie" all the way home.
Around that time we ran across several Regina freewheels that were locking up. We took them apart and they were full of metal chips. This included the cheap ones all the way up to the Oros. Must have been a labor problem???
