UPDATE:
Brompton has sent a replacement wheel for my bike. Im very happy this chapter is soon to be closed with good faith.
Recap:
I bought a super awesome sl6, from a brompton lbs that closed shop. The 3 speed hub started feeling crunchy, not smooth. Contacted Brompton, and the lbs. The Brompton LBS shut down, so now i was without a dealer to work the claim. After much back and forth England contacted NY for help with this matter. And my road bike lbs is being a bridge for the claim.
Now Brompton is in for a complete over haul and wheel install.
