  14. Bridgestone has used them for over 5 years on their Picnica folding
  15. bicycles.  They are clean, use an ingenious self-tensioning device to
  16. keep them from slipping under load, and cannot be shifted.  They are
  17. typically used in conjunction with a coaster brake or N-speed hub.  I
  18. do not know their efficiency or weight.
